Hennepin County and their project partners have completed the planning, preliminary design, and detailed final design for the reconstruction of CSAH 5, the Franklin Avenue Bridge, over the Mississippi River. The reconstruction of this bridge, which is listed on the national register of historic places and is a City of Minneapolis Historical landmark, includes:
- Concrete rehabilitation of the substructures during the 2015 construction season.
- Fabrication of precast deck panels at a project specific casting yard established near the project site during the 2015 construction season.
- Demolition of the existing deck and cap beams and erection of the precast deck panels using an accelerated schedule. This work will take place between June 8 and August 31, 2016.
- The addition of pier over-looks and concrete barrier to enhance shared use paths.
- Reconstruction of the approaches.
- Minor grading and roadway work. This is primarily on the west side of the bridge and will improve pedestrian access in the area.
- Work in a navigable water – the Mississippi River.
- Work within an environmentally sensitive area.
- Traffic impacts
SRF was selected to be an integral part of Hennepin County’s construction administration team by providing three full-time bridge inspectors to assist County staff with precast inspection, bridge inspection, quality documentation, and material testing.
