About this Project
The purpose of this assignment was to provide engineering design services for the complete replacement of overhead Bridge EB-311, which carries SR 441 (North Union Street) over the PTC Mainline. The bridge replacement provided sufficient horizontal and vertical clearance to accommodate the total reconstruction of the Mainline in this area. AEG’s responsibilities included the development and execution of subsurface investigations in coordination with the PTC’s Open-End Boring Contract, in-house laboratory testing, geotechnical analyses and recommendations, foundation design, infiltration investigations, and pavement design assistance.
