The Mon-Fayette Expressway:  Pittsburgh to PA-51 Section

NEW!  For aerial views of the North Shore Alternative, please click here.

PLEASE ALLOW A MINUTE OR SO FOR THIS DETAILED MAP BELOW TO LOAD

    The map shown above shows a more detailed area that is currently being studied for this section of the project.  Since this project is still in the preliminary alternatives phase, changes to this map is certainly possible.  This map will be updated as we get those changes.

    NOTE THAT IN THE MAP ABOVE, THE SQUARES INDICATE A TOLL BARRIER ON THE EXPRESSWAY, FULL CIRCLES INDICATE A FULL INTERCHANGE AND THE HALF-CIRCLES INDICATE HALF-DIAMOND INTERCHANGES.

    To orient you, Jefferson Boro and Route 51 is at the bottom (South) and Pittsburgh and I-376 (Parkway East) is at the top (North).

    Seven preliminary alternatives (four of which involved construction of a new tolled expressway and three of which involved various other measures to upgrade the existing highway system) were presented to the general public at meetings held March 14, 1996, at Gladstone Middle School in Hazelwood, March 19, 1996, at West Mifflin High School and March 20, 1996, at Olympia Hall in East Pittsburgh.  Three of the four expressway alternatives included a "Thompson Run Connector" that would begin on the north bank of the Mon River near the USX Edgar Thomson works and continue north through the Union Railroad/Thompson Run Valley to the Parkway East (at a point between Churchill Borough and PA Route 48 in Monroeville).

    The approximate length of the Route 51-to-Pittsburgh project is 24 miles.

NORTH SHORE & SOUTH SHORE ALTERNATIVE OPTIONS

NORTH SHORE& SOUTH SHORE ALTERNATIVES

 (refer to map above)

Option 1 A - This option requires the acquisition of 3.4 acres of the West Mifflin Park property near the entrance.

Option 1 B - Since publicly-owned parks and recreational areas are protected by Section 4(o of the Federal Transportation Act of 1966, Option 1 B is being considered to avoid impacting the West Mifflin Park property.  However, this option would result in sixteen displacements in the New Colony Mobile Home Park.

Option 2A - This option would place both the northbound and southbound lanes of the Expressway on structure between the Penn Plaza Shopping Center and St. Colman's Church.  With this option, the current Penn Plaza building would be acquired and then possibly relocated along Church Street with parking under the Expressway.

Option 2B - This option would place both northbound and southbound lanes of the Expressway on structure through the Penn Plaza parking lot, along Church Street.  This option would not require the acquisition of the Penn Plaza building, but would negatively impact parking for the shopping center.

Option 2C - This option would split the southbound lanes of the Expressway on structure between Penn Plaza and St. Colman's Church and the northbound lanes would be on structure through the parking area for Penn Plaza.  This option would not require the acquisition of the Penn Plaza building, but would also negatively impact parking for the shopping center.

NORTH SHORE ALTERNATIVE

Option 4A - This option would result in the Expressway being elevated along the hillside on retaining walls.

Option 4B - This option would result in the Expressway being elevated along the hillside on structures.

Option 5A - This option would construct the Expressway depressed below grade on the existing CSX mainline railroad corridor through Lower Hazelwood.  For this option, the CSX mainline would be relocated along the Monongahela River.  A ramp from the Expressway (traveling from Pittsburgh) to the LTV Site would be provided for this option, however this option would not provide any improvements to Bates Street at the interchange with 1-376/Parkway East and Second Avenue.

Option 5B - This option would construct the Expressway depressed below grade on the existing CSX mainline railroad corridor through Lower Hazelwood.  For this option, the CSX mainline would be relocated along the Expressway, however it would not provide a ramp from the Expressway (traveling from Pittsburgh) to the LTV Site.  It also would not provide any improvements to Bates Street at the interchange with 1-376/Parkway East and Second Avenue.

Option 5C - This option would construct the Expressway depressed below grade on the existing CSX mainline railroad corridor through Lower Hazelwood.  For this option, the CSX mainline would be relocated along the Monongahela River.  This option would include a ramp from the Expressway (traveling from Pittsburgh) to the LTV Site.  This option would also widen Bates Street to the Boulevard of the Allies, provide improved access with 1-376/Parkway East and provide access to Second Avenue.

Option 5D - This option would construct the Expressway depressed below grade on the existing CSX mainline railroad corridor through Lower Hazelwood.  For this option, the CSX mainline would be relocated along the Expressway, however it would not provide a ramp from the Expressway (traveling from Pittsburgh) to the LTV Site.  This option would widen Bates Street to the Boulevard of the Allies, provide improved access with 1-376/Parkway East and provide access to Second Avenue.

SOUTH SHORE ALTERNATIVE

Option 6A - This option would not provide any improvements to Bates Street at the interchange with 1-376/Parkway East and Second Avenue.

Option 6B - This option would widen Bates Street to the Boulevard of the Allies, provide improved access with 1-376/Parkway East and would provide access to Second Avenue.
