The Missing Ramps, Under Construction
M.A. Beech Corp. was awarded this project in April of 2006 which is anticipated to begin in the summer of 2006 and be completed at the end of the 2009 construction season. It is estimated that construction will be over $50 million.
Since late 1973 when the three level stack interchange of I-79/I-279 opened to traffic at a cost of $14M, the most expensive interchange ever built in the Commonwealth at that time; the Route 60 corridor has experienced enormous growth in commercial and residential customers. However this interchange did not include two ramps: one ramp connecting SR 79 southbound to SR 22/30 westbound; and the other ramp connecting SR 22/30 westbound to SR 79 northbound. In late 2002, the Southwestern Pennsylvania Commission approved shifting state and federal funds to the construction of these long overdue ramps. Currently the missing ramp traffic movement is accomplished via SR 60 which has interchanges at SR 79 and SR 22/30.
Mosside Bridge, Completed 2008
M.A. Beech began this project in March of 2006 and was
completed in the first part of 2008. There were four inspectors on this $16.6 million project.
SR 48 (Mosside Blvd.) is a vital link for the South Eastern suburbs and Norfolk Southern Railroad Intermodal Terminal to the Monroeville business district and the Pennsylvania Turnpike’s Pittsburgh Toll Plaza. This 4-span, 812 foot bridge was first erected in 1930 by Allegheny County and its deck height is approximately 70 feet. Construction will consist of removal of the existing structures, total reconstruction of approach roadways, milling and resurfacing of existing pavement, installation of both temporary and permanent traffic signals, stream relocation, storm water management facilities, removal of a portion of pile/plank retaining wall, construction of new pile/plank retaining wall, relocation of sanitary sewer line, construction of temporary causeways on Turtle Creek for construction access, construction of a rigid frame structure carrying SR 48 over an access road, and construction of dual structures over Turtle Creek and the Norfolk Southern Railroad.

The official name for the Mosside Bridge is
Allegheny County Bridge No. 4 Turtle Creek.
Parkway West is the main artery into downtown Pittsburgh from the south and the west and from Pittsburgh International Airport. The project involved overlaying a 6.1-mile stretch of this interstate in both directions, beginning at the exit from the Fort Pitt tunnels. The water job was complicated by the fact that water could not drain away from the underlying concrete pavement, which was abutted by a concrete shoulder on the outside lane and a concrete median barrier on the inside. This was a $7.8 million construction project, and M. A. Beech’s staff of ten inspectors were responsible for the inspection and documentation and received an evaluation of 97% from the Department of Transportation.
This project was completed in eight weekends; and at times road construction was affected by special sporting events in the area or by holiday traffic. The project was further complicated by wet weather. Rain postponed the first scheduled weekend of work and affected at least five other weekends.

M.A. Beech staffed, at peak, over 35 inspectors for inspection and documentation and received a good evaluation from PennDOT’s District 11-0.
First opened on June 19, 1959, the award winning Ft. Pitt Bridge/Tunnel project is a steel bowstring arch; double-deck design, the arch is riveted plates, cross-bracing on arch is warren truss made of oval-perforated beams, suspenders are wire cable, the deck is riveted plates in warren truss and the piers are faced with dressed stone. The length of the main span is 750 feet and total length is 1217 feet including the longest elevated ramp, with a height deck of 47.1 feet. This bridge crosses the Monongahela River at mile 0.2; CSX Railroad (P&LE), East Carson Street; and NS (Conrail) Railroad.
