MCKINLEY GRADE SEPARATION - CORONA, CA
Meroe Engineering provided CM services including Structure representative for the construction of steel tied-arch bridge grade separation. The improvement allows for vehicles to cross over a main local street, water canal, and rail-road tracks uninterrupted in order to reduce traffic, increase safety, and improve access to local businesses. The steel structure was erected on temporary supports adjacent to the final location prior to being moved into place using self propelled modular transporters. Approximately 43,000 SF of MSE panel wall, 13,000 SF of architectural treatment, and 1,100 CY of cast-in-place retaining wall was constructed in order to allow for the grade separation and ramp widenings. The project contained 5 foot columns on 7 foot CIDH piles with ground water and caving soils. Private and public utilities required relocation including water and sewer lines; communication lines; and irrigation. Grade crossings included work over BNSF railroad right-of-way.
The project was completed in on-going.
