This $177M project includes the reconstruction of two ramps located at the SR 91 / SR 417 interchange. FINLEY provided preliminary bid estimates, value engineering, temporary works design, construction engineering and analysis for the following ramps:
- Ramp A2 (northbound SR 91 to southbound SR 417) includes the construction of a 1,882 ft-long, 9-span, third level steel box girder bridge. The design modifications include removal of the diaphrams and modifications to the erection sequence.
- Ramp C2 (southbound SR 91 to northbound SR 417) includes the construction of a 1,455 ft-long, 6-span, third level steel box girder bridge. The design modifications include a redesign of the substructure, a redesign of the steel box girder, modifications to the span arrangements and a revised erection sequence.
