The story on how the unbuilt US 40 Expressway in Brownsville took 40 years to complete.

This abrupt end to US 40 east of Brownsville was the norm for nearly forty years. (Brian Reynolds)
For nearly four decades, the four lane US 40 just east of Brownsville came to an abrupt end - shown in the photo above - at Grindstone Road in Redstone Township.   In the late 1960s, what was then the Pennsylvania Division of Highways (PennDOH) extended a new four lane alignment of US 40 eastwards from Broadway Street slightly over one mile to Grindstone Road where an incomplete diamond interchange was built.  Earlier in the decade, PennDOH had built a four lane US 40 in Washington County into Brownsville complete with a new crossing over the Monongahela River known as the Lane Bane Bridge.  This new highway and bridge allowed US 40 to bypass the older Intercounty Bridge and downtown Brownsville. 

Brownsville in September 1967.  US 40 crosses over the new Lane Bane Bridge and a trumpet interchange with PA 88 sits in Washington County.  The Intercounty Bridge sits just south of the Lane Bane Bridge.  Construction on the US 40 four lane extension to Grindstone Road doesn't appear to be underway yet. (Penn Pilot)

After this new highway opened, nothing would happen to it for nearly forty years.  US 40 traffic would use the ramps for this planned diamond interchange and then jog on Grindstone Road briefly before continuing towards Uniontown on the original National Road. 
What is unknown (at least to me) is that what was supposed to have continued southeast or east from Grindstone Road.  Was it a separate US 40 that would have continued towards Uniontown? Or part of the original Mon Valley Expressway?  Or something else? Official PennDot maps of Fayette County (above at right) would never show any proposed or planned route beyond the interchange.

If it was to be part of the Mon Valley Expressway, it would have been part of the original or early proposed alignments.  The Mon Valley Expressway would see its shape change many times since the 1950s.  It could have also been one of the many possible connector routes that were planned to the Expressway to and from the various towns along the Monongahela River.  No matter what it was to continue as or towards, nothing would happen here until the later half of the 2000s.  It was then, that this old unused piece of expressway would be converted to a two lane at-grade roadway connecting US 40 and Brownsville to the Mon-Fayette Expressway.

Personally, I first came across this stub end in the early 1990s when going to watch my high school football team play Brownsville Area High School.  We came upon it via Grindstone Road.  Grindstone Road would briefly turn into a four lane boulevard type road and crossover the never completed highway.  During the 1990s, I would drive out to explore this area to search for any clues on what was never built here.  I've included some photos of how it looked in 2002 when a number of us toured this oddity.

Grading for the never built highway was still evident even with the overgrowth.  (Bee Family)
This overpass carried Grindstone Road over the unbuilt highway.

Right of way and clearing was done beyond the overpass to what would have been the eastern end of the ramps for the diamond interchange. (Bee Family)

Not long after those photos were taken, the Pennsylvania Turnpike Commission would begin construction to finally extend this route southeastwards towards Uniontown.  Known as the Redstone Connector, the roadway was built as a two lane highway that is served to connect US 40 and Brownsville to the Mon-Fayette Expressway.  The highway, though built as two lanes with a center turning lane, can be expanded to a four lane road keeping the center turn lane if traffic volumes and development warrant.  The diamond interchange with Grindstone Road would not survive the construction.  It was eliminated and changed to a normal signalized intersection.  A return visit in December 2006 showed construction well underway on the Redstone Connector and the new roadway would open one year later in December 2007.

The eventual construction of Redstone Way is a rare case in Western Pennsylvania and actually throughout Pennsylvania of long shelved highway plans coming to life and completion.  Although it is unknown what the original plan for US 40 east of Brownsville was, the stub ends of a highway that would go nowhere for nearly forty years found a new purpose and an ultimate destination.  If you have any background information on what any of the proposed plans for US 40 in Brownsville were to be, please shoot me an email or leave a comment.

Check the box: Interstate 495 to 87 conversion administratively approved

The American Association of State Highway and Transportation Officials have recently approved North Carolina's application to remove the short-lived Interstate 495 and future I-495 from Raleigh to Rocky Mount.  This administrative move most likely will result in North Carolina signing Interstate 87 and Future I-87 on the entire corridor in the near future.

Approved in 2013, Interstate 495 was first signed in 2014 along US 64 from Interstate 440 in Raleigh to Interstate 540 in Knightdale.  The remaining segment of highway to Rocky Mount was signed as Future Interstate 495.  However, in 2016, North Carolina's congressional legislators were able to get language in the 2015 FAST ACT designating the US 64/US 13/US 17 corridor from Raleigh to Norfolk as an Interstate.  In 2016, the FHWA and AASHTO designated this entire corridor (including the existing Interstate and Future 495) as Interstate 87.  (NCDOT had applied for Interstate 89 along this route.)

It is currently unknown when t…

A quick Illinois and Wisconsin Road Trip

Recently, I was in the Chicago area and was able to explore the area north of Chicago and Wisconsin in my downtime.  I pretty much did a loop that consisted of Interstate 94, Interstate 43, US 12, Illinois Route 120, and Illinois Route 60.  It was my first real time exploring the area.  I ended up gaining an additional five counties on the trip bringing my total to just short of 1100, 1099 to be exact.

For the entire flickr set of photos for this trip, please head here.

Just prior to entering Wisconsin on Interstate 94, you will come across this sign.  Out of nowhere, Interstate 41 appears.  And if you aren't hip to changes on your map, Interstate 41 is a rather recently new interstate that runs from Green Bay to just about a mile inside the Illinois border.  Interstate 41 is an upgraded routing of the US 41 freeway that runs from Milwaukee to Green Bay; however, it was added along Interstate's 894 and 94 South of Milwaukee to where US 41 leaves I-94.  In fact, throughout the…
