SR 1008 Gulf Lab Road Bridge

Gibson-Thomas Engineering, as a sub-consultant to Figg Bridge Engineers, designed the Gulf Lab Road Bridge Replacement as part of a larger project to replace the mainline Turnpike crossing of the Allegheny River. The new Gulf Lab Road structure is a 2-span continuous steel plate girder bridge.

Gibson-Thomas Engineering worked closely with other design team members to prepare the design of a soil nail/rock anchor retaining wall adjacent to the mainline turnpike and under the Gulf Lab Road structure. The retaining wall is over 1,100 feet in length with a maximum height of sixty feet. Construction cost of the bridge, retaining walls and S.R. 1008 roadway approaches was bid at more than $5,000,000.
