New bridges, new approaches, new STH 20.

This project included the preliminary and final design for the reconstruction of two bridges as well as a deck replacement and rehabilitation of a single-span bridge along STH 20.

The project involved replacing existing bridges with single flat slab superstructures supported on A5 type abutments for two bridges and replacing the deck on a prestressed concrete single-span bridge. The project also included field survey, a structure survey report, a hydraulic report, geotechnical investigations, and preliminary and final roadway and bridge plans.
