PennDot opens bids on completing I-79/Parkway West Interchange

....thirty years later.

PennDot opened bidding on the construction of two "missing" ramps at the I-79/Parkway West (I-279/US 22/30) interchange (Exits 59A-B) in suburban Pittsburgh. I say "missing" because these ramps were not planned for in the original construction of the highway in the 1970s. The missing ramps are from I-79 South to US 22/30 West and US 22/30 East to I-79 North. Construction should start this fall and the ramps should open in 2009.

When the interchange was constructed in the early 1970s, I-79 actually was planned to actually take the ramp from I-79 onto the inbound Parkway West (I-279 North). I-279 would continue straight on what is now I-79 North today. But that changed when I-79 and 279 switched alignments in 1972. Anyways, the thinking at the time was that connections from I-79 South to the Airport and from the Airport to I-79 North could be done via PA 60 -- then a rural two lane road -- and connecting at what is now Exit 60. The hope was that PA 60 would be upgraded to at least a four lane divided highway or even a more limited access highway. Well, that along with many other highway plans for Pittsburgh never happened.

So thirty years later, a major freeway to freeway interchange is incomplete. Until 2009, that is. The interchange will become a three level stack interchange as the new ramp from US 22/30 East to I-79 North will fly over both highways. Also -- and you don't hear this at all in Western PA -- US 22/30 will be widened from four to six lanes from the I-79 interchange to the newly rebuilt Campbells Run Road intechange. A total of 1.6 miles. (For Pittsburgh, that's impressive.) I do not know as it's been years since i have traveled it, but I think that with the widening US 22/30 will be six lanes from I-79 to the PA 60 interchange (another incomplete interchange). But I may be mistaken about that.

Here's the story in Friday's Post-Gazette:

Commentary:

Although relatively small, this is an important improvement to Pittsburgh's highway system and the airport corridor. Since the early 1990's, the corridor has seen the completion of the Southern Expressway (A Freeway PA 60 connecting to the new airport terminal), there have been numerous upgrades to PA Business 60 (The old airport parkway), The West Busway, the Findlay Connector scheduled to open sometime in October 2006, and now completion of the I-79/Parkway West ramps. You gotta take what you can get.

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

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. 

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…

The story of the Boy Scout Ramps on Interstate 79 North in NW Pennsylvania

If you are traveling on Interstate 79 North of Pittsburgh, you may notice the remnants of a set of off and on ramps at mile 100 just north of Exit 99 (US 422).  There's a story behind these ramps.  Forty years ago, these ramps were built specifically for two Boy Scout Jamboree's that were held at Moraine State Park - 1973 and 1977.  The ramps purpose were to provide access to the north shore of Lake Arthur where the bulk of the festivities and campsite for the Jamboree were located.  (Lawrence County Memories has a great write up and map of the festivities on its site.)

Not long after the Jamboree ended the ramps were abandoned.  There are still remnants of the Boy Scout Ramps today.

The google street view image above gives a view along West Park Road of where the set of ramps intersected the highway.  The ramps provided direct access to North Shore Drive (which is the right tur…

The few clues of the Northern Durham Parkway

Sometimes when you look through a box of maps for the first time in five years, you come across something you may have easily over looked.  Such was the case when I found a 2004 (so rather recent) map of Raleigh.  This map was made by the Dolph Map Company for WakeMed.  In the Northwestern corner of Wake County, there were two items to the map showing roads that are still not in existence 13 years later.

The road is the Northern Durham Parkway - this is a proposed 19 mile highway from US 501 north of Durham to the Raleigh-Durham International Airport.  The first proposals for this highway date back to 1967 when Eno Drive-Gorman Road was listed on the Durham Area Thoroughfare Plan. (1)  Other proposals called the highway the Northwest and Northeast Durham Loop. (2)  The route would serve as a northern and eastern bypass of Durham almost serving as a near loop.  The route was fought vigorously for three decades by the Eno River Association citing concerns for the the Eno River, nearby n…
