The first photo of this mult-day, multi-state road trip comes from Grayson, Ky., where US 60, KY 1 and KY 7 intersect.

KY 1 and KY 7 run concurrently north of US 60 in Grayson, past I-64 and the AA Highway (KY 9) to a point a few miles north, where they split.

New guide signage was installed along KY 1 and KY 7 as part of a project a few years ago to reconstruct this interchange.

A guide sign lists the standard control cities for I-64.

This is one of the new Clearview signs for the KY 180 exit that is currently being reconstructed.

Another Clearview sign; this one is a bit unusual because there is no white border or separator line between the brown and green portions of the sign.

I-64 is routed onto two-way traffic in the westbound lanes during the Exit 185 reconstruction project. Traffic bound for the exit stays in the right lane; I-64 through traffic stays left and uses a median crossover.

A reasurrance marker for the two-way configuration of I-64.

A look at the Exit 185 reconstruction project. A new exit ramp from westbound I-64 to KY 180 has already been built; the other ramps are under construction. This is looking east.

At the top of a hill east of Exit 185, I-64 returns to four-lane status. Traffic entering eastbound I-64 from KY 180 joins on the right side.

This sign in Kentucky is for Exit 1 in West Virginia.

Jumping ahead into West Virginia, this photo is of the bridge reconstruction project at the Milton exit.

Moving further ahead, after passing through a downpour that lasted from near Hurricane to past Mink Shoals, this sign is on northbound I-79 and will be submitted to roadsignmath.com as a winner.

A vertical shot of the same sign.

Yet another shot of the mathematically-significant sign.

This sign is a winner, as well. The math on this one is pretty simple.

I exited I-79 for a short trip south on US 19, a/k/a Appalachian Corridor L.

At the top of the ramp, a US 19 sign.

This sign directs traffic from the local road that ties into US 19 that the northbound highways can be reached via a left turn.

Overhead for US 19 south.

Birch River is the first small town enountered on the route. Corridor L terminates at the West Virginia Turnpike at Beckley.

Unique mile markers have been installed on all the ARC corridors in West Virginia, and US 19 is no exception.

A standalone US 19 marker.

Typical view of US 19. This bridge crosses the Little Birch River.

Approaching WV 82.

At the WV 82 exit. Webster Springs is also signed as a destination at this exit.

Beyond the Birch River exit, Muddlety is the terminus of WV 55.

Between Birch River and Muddlety, US 19 climbs a mountain. Each side has a truck lane on the uphill climb.

Another look at the mountain ascent.

The summit of Powell Mountain.

On the other side of Powell Mountain is Muddlety and the terminus of WV 55, a multi-state route that spends much of its time in West Virginia co-signed with other highways. In Virginia, it parallels I-66 and runs nearly to the Washington D.C. suburbs.

One mile from the Muddlety exit.

Several tourist attractions can be found in this section of West Virginia, and WV 55 runs to or by many of them.

Two more towns that can be reached via WV 55.

At the Muddlety exit.

The ramps along the exits on Corridor L have indicator signs.

Turning left from the exit ramp puts you on WV 55. At the right is a WVDOT maintenance facility.

The first WV 55 marker as you head east.

Mileage sign on WV 55 with destinations both near and far.

At this spot, WV 55 runs along the alignment of old US 19, which goes straight. WV 55 turns right. It used to be numbered WV 43 until WV 55 was extended west and south from its original terminus at Moorefield.

Typical view of WV 55 between Muddlety and Craigsville.

This is the northern terminus of WV 41, which runs from here south to Summersville and then follows the old route of US 19 to Beckley.

WV 55 runs to Craigsville, where it joins WV 20 south to Richwood. WV 20 north goes to Webster Springs.

Approaching the intersection of WV 20 in Craigsville.

Signage at WV 55 and WV 20. The Rite Aid appears to be the largest business in the crossroads town of Craigsville.

Heading north on WV 20 out of Craigsville.

Unusual that "Springs" is spelled out on this sign. Probably because there's room on this sign because "Camden On Gauley" is a long name.

Approaching WV 82.

WV 82 heads back to Birch River and US 19.

Nice collection of signs showing Interstate, US and West Virginia state routes.

This hairpin turn is on WV 20 heading down the mountain into Webster Springs.

This bridge is one of two that WV 20 crosses heading into Webster Springs.

Intersection of WV 20 and WV 15 in downtown Webster Springs.

Heading up the mountain out of Webster Springs, which is wedged tightly into a valley.

This photo didn't turn out too good so I turned around, went back, and tried again.

This one didn't turn out much better (low light conditions because of shade from trees and overcast conditions). Anyway, it has a mistake. The mileages to Buckhannon and Flatwoods are reversed. It's actually 37 miles to Flatwoods and 53 miles to Buckhannon.

A truck turnout lane helps faster traffic pass slower traffic on WV 15 & WV 20 going north out of Webster Springs.

This sign is at Diana, approaching the split of WV 15 and WV 20. The directional arrows are missing from this assembly.

Your choice of destinations at the split of WV 15 (left) and WV 20 (straight).

Signage at the split of 15 and 20.

Heading up a mountain immediately after 15 and 20 split. Rock Cave is where WV 4 terminates.

Interesting how much this sign looks like the old Kentucky Mountain Parkway sign. All it needs is a lone tree standing beside the winding road.

Standalone WV 20 sign past the WV 15 intersection.

This is how WV 20 looks as it climbs the mountain north of Diana.

At the summit of Hodam Mountain.

Another WV Byway "Mountain Parkway" sign.

Interesting bridge design with the modern concrete barrier walls and the metal arches.

Do the math on this one ... which will definitely be submitted to Road Sign Math.

There is also a "Backway" sign with the Mountain Parkway name. It's reversed with green where blue is on the "Byway' sign, and vice versa.

Approaching WV 4 at Rock Cave.

Many years ago, WV 4 joined WV 20 here. Now WV 4 has been truncated to this location.

Getting closer to Buckhannon.

Sago was the site of a well-known coal mine disaster. WV 20 does not run through the small town but it runs close by.

Closeup of the Sago Road sign.

County 22 is known as the Coal Miner's Memorial Roadway in honor of those who lost their lives in the Sago disaster.

A view of the Coal Miner's Memorial Roadway with the sign.

South of Buckhannon, signs are posted to direct traffic out of downtown over to the four-lane Corridor H.

In downtown Buckhannon, strawberries are painted all over the streets. Must be in honor of a local festival or something.

In downtown Buckhannon, WV 20 crosses the old routing of US 33. This sign tells drivers to keep going north on WV 20 to get to the new highway.

At the same intersection are these signs.

Approaching Corridor H north of downtown Buckhannon.

WV 57's terminus approaches.

At the terminus. Traffic heading south on US 119 is also guided to I-79 via WV 57.

Obscured by trees is this signage for Truck US 250 in Philippi, which diverts heavy traffic off the famous Philippi covereed bridge.

Looking at the intersection.

This sign is approaching the split of 119 and 250. It says "JCT US 250" even though you are already actually on US 250.

Advance signage for the split.

At the split of the routes.

Grafton is three miles away and it's a bit further to Morgantown.

After passing through downtown Grafton, US 119 intersects US 50.

We've come at leas three miles since the last mileage sign and it's STILL 26 miles to Morgantown.

This US 119 sign north of Grafton features a full-width directional banner that is also proportionally taller to match.

Approaching I-68, this sign does not have a state name. There are a few of these in the Morgantown area. This photo was taken in a driving thunderstorm, along with the next several.

These I-68 signs do have the state name.

Approaching County 857, this sign erroneously marks it as a full-fledged state primary route.

The overhead is correct, however.

An untimely pass of the windshield wiper (it was pouring the rain, after all) partially obscured the view of these signs featuring two standalone county route markers and one US marker.

Still raining -- this sign directs CR 857 traffic toward WV 7.

Signage showing that CR 857 joins WV 7 for a signed multiplex.

These signs show that CR 857 is fully posted.

The combination of WV 7 and CR 857 is posted as the routes join for a short distance.

CR 857 is also signed along with US 119.

CR 857 follows a new four-lane access route to I-68.

One I-68 sign with the state name, one without.

This is the crossing of CR 857, old WV 73, over Cheat Lake. The bridge has an open metal grate deck and is only about 1 1/2 lanes wide.

Looking at the eastern end of the bridge.

Looking up at the I-68 Cheat Lake crossing.

Work is ongoing near the access route from CR 857 to I-68 at Cheat Lake.

This photo was shot from WV County 88/1, Bowers Lane, near Cheat Neck. It shows the unfinished WV 43, the Mon-Fayette Expressway. The nearest lane is the northbound lane and the far lane is the southbound lane. Presumably the overheads are for what will be the I-68 interchange, I was unable to see the fronts of the signs.

This shows where the pavement and guardrail end on the unopened portion of WV 43.

These bridge piers are under construction where WV 43 will cross CR 71, Morgan's Run Road. The clouds in the distance are the ones that were putting down a downpour in the thunderstorm that caught me in Morgantown.

Looking at the south bridge abutments where the Mon-Fayette will cross CR 71. The southbound lane is at right and the northbound lane is at left.

Entering Pennsylvania, where Monongalia County 857 becomes PA 857.

First PA 857 sign.

Not far from the state line, Gans Road connects PA 857 with PA TPK 43 and US 119.

Trailblazer for PA 43.

The PA 43 interchange is within sight of PA 857.

Approaching the entrance to PA 43.

First PA 43 sign is located just beyond the Gans Road overpass.

This exit is the first one on the completed portion as you head northbound.

Heavy trucks should use the next exit.

Overheads for the access ramp to the turnpike.

Older I-70 sign (see the peeling "0") with the state name.

Typical view of I-70 heading west out of New Stanton. The design is much like the PA Turnpike, with a Jersey barrier right up against the left lane. The speed limit here is 55 mmph but most traffic was flowing at 70 or faster -- mostly faster.

When we last saw PA 31, it was intersecting US 119.

Overheads at the PA 31 interchange.

PA 51 is a major highway in this section of the state.

Overheads for the PA 51 exit.

Another exit along I-70. When the exits were converted from sequential to mile-based, the old exit number was posted and it remains so in most places.

Overheads for the PA 201 exit.

The speed limit drops from 55 mph to 45 mph, for no apparent reason, in the Belle Vernon area where the interstate crosses the Monongahela River.

A look at the massive metal arched truss Monon River bridge.

Crossing the Monon River. Note the lack of shoulders on either side.

On the other side of the Monongahela is the PA 88 exit.

Another iteration of PA TPK 43. Eventually this road will link with the portion heading south from Uniontown toward West Virginia. Now it exists in discontinuous segments.

Overheads for PA TPK 43.

This ground-mounted PA 43 sign seems out of place on the interstate.

Bridge-mounted signs for Exits 37 and 36. Interesting community name there for Exit 36.

Exit 35 guide signage.

An older bridge design can be seen here at Exit 32B.

Another instance of an older bridge design at Exit 32A.

Old arched metal bridge deck that carries PA 917 across I-70.

Another older-style bridge abutment design can be seen here.

Home of the famous 84 Lumber company. Which came first, the business or the town name? Inquiring minds want to know.

Note the Jersey barrier is still in place as I-70 nears the interchange with I-79. You can see where the barrier ends in the distance. Curious, too, that the state name is located on most all signs for Washington, Pa. (to avoid confusion with Washington, D.C.) even though this is practically at the limits of Washington, Pa., yet the state name is not used for an out-of-town control city such as Morgantown.

The end of the Jersey barrier as the divider widens to a more standard grass median.

Overheads for the I-79 and I-70 intersection.

On Pennsylvania exit gore signs where interstates intersect, the interstate number and direction are posted.

This Clearview sign directs through traffic to use the left lane as the joined highways approach the exit areas for Washington.

Overheads for two of the Washington exits.

Overheads at US 19.

Overheads for the split of I-70 and I-79.

At the split.

Beyond I-79, still more exits for Washington.

I-70 hasn't touched US 40 since way back at Hancock, Md., where 40 leaves I-70 to join I-68. I-70 jogs north and joins the PA Turnpike while US 40 runs west past Cumberland, Md., then turns to the northwest.

Moving on past Washington and heading toward West Virginia, this is the third exit (or second-to-last) in Pennsylvania.

Clearview mileage sign.

Clearview strikes again.

And again.

And yet again.

This is the last exit in Pennsylvania.

Entering West Virginia on I-70. Note the same style of gantry that is heavily used in the Charleston area.

Typical view of I-70 shortly after entering West Virginia.

The first exit in WV is for County 41.

Cabela's, the sporting goods/outdoors store, has build a big showroom and retail facility that is a tourist destination in and of itself, east of Wheeling. This exit was built to allow access to the store from I-70.

At the Cabela Drive exit. You can't see the Cabela's but you can see a Cracker Barrel.

Heading down a mountain, I-70 approaches the I-470 bypass.

Overhead diagrammatical sign for I-470 and I-70.

Just before the split of I-70 and I-470, I-70 intersects US 40 (again) and WV 88.

This sign warns of the Wheeling Tunnel. Oversized loads and hazardous cargo trucks are instructed to use I-470.

Overheads for I-470, US 40 and WV 88, in button copy.

Lane splits for I-70 and I-470 in button copy.

The first I-470 sign, appearing a little out of focus due to motion blur.

Overheads as I-470 adds a truck climbing lane.

These mile markers, which can be found in many larger cities these days, have been installed on I-470 in the Wheeling area.

Another I-470 sign.

I-470 descends toward the Ohio River and the exit ramp to US 250 and WV 2 is even steeper.

The Ohio River bridge is in the distance behind the overheads for US 250, WV 2 and OH 7.

The interchange between I-470 and US 250/WV 2 is known as a "volleyball" interchange. These overheads are at the end of the ramp from westbound I-470. The bridge in the background carries US 250/WV 2.

On the "volleyball" collector-distributor ramp. This one is a bit unusual because it also allows access to 26th Street

Overheads for the departure of WV 2 from US 250.

More overheads for the WV 2/OH 250 split. Interesting that the state name is used on PA's signs but not on these WV signs.

In downtown Wheeling and off the freeway, WV 2 makes a number of turns.

Here is another turn.

Because of construction, the eastbound lanes of I-70 were shut down in the Wheeling Tunnel. That's why these signs have some temporary decorations on them.

Traffic for east I-70 is detoured onto I-40 east. Below the "WV 2 Weirton" sign you can actually see the western portal of the Wheeling Tunnel.

Overheads where the ramp to westbound I-70 splits off the ramp that carries northbound WV 2.

Looking at overheads where US 40 and WV 2 intersect.

Eastbound US 40 takes the street to the right. Westbound US 40 and northbound WV 2 turn left.

WV 2 south is a two-lane road that comes in from the right. Northbound WV 2 turns right to end the one-way splits here.

North of Wheeling, there are a few four-lane sections of WV 2 such as this.

Among the state routes that WV 2 intersects in the Northern Panhandle is WV 67.

At the WV 67 intersection.

Getting closer to Weirton and WV 2's intersection with US 22.

WV 2 and WV 27 intersect.

Trees obscure the signage at the intersection.

Alt. 27 and 27 never intersect each other but they both terminate at WV 2.

At the terminus of Alt. WV 27.

Just south of Weirton, WV 2 expands to four lanes north of Follansbee.

WV 2 approaches US 22.

This type of sign is common on four-lane surface routes in WV.

Button copy overhead for US 22.

Overheads for WV 2 and US 22, in button copy, and with state names for the out-of-state cities.

The overcast skies and fading sunlight made for some motion blur, but this sign directs traffic heading from WV 2 onto US 22 which is headed for Pennsylvania to move to the left lane.

Button copy overheads showing lane designations for the brief multiplex of US 22 and WV 2.

The first exit for US 22 in Pennsylvania is in Clearview.

Approaching the exit for the new PA TPK 576. Surprisingly, these exit signs are not in Clearview.

At the PA TPK exit off eastbound US 22.

The interchange is another "volleyball" style. Currently the toll road only connects US 22 and PA 60. Eventually the loop is supposed to be finished around to at least I-79 somewhere in the Bridgeville area.

Overheads on the C/D lanes within the "volleyball" interchange. Although 576 is really heading northeast, it's signed as "west" because when the loop is eventually finished, a right turn here will have you traveling east toward I-79.

On the other side of the interchange are these overheads.

The toll booth as you enter 576.

The first exit is for the communities of Bavington and Santiago.

The first PA TPK 576 sign.

At the bridge carrying 576 over 30, this overhead shows the lane splits for the end of 576.

Another overhead, this one where inbound traffic from US 30 merges.

Exit Only overheads as 576 nears its terminus.

A look at the diagrammatic sign for the airport and PA 60 south.

End sign for 576 at the end of the bridge where the ramp crosses PA 60 and begins looping around to the northbound Beaver Valley Expressway. There is also an end sign for traffic heading toward south PA 60.
