US 64 (State Route 40) Bridge ReplacementPolk County
Transportation projects are developed in four phases: Planning and Environmental, Design, Right-of-Way (ROW), and Construction. In an effort to expedite project delivery, the US 64 bridge replacement will be completed under a Design-Build contract. The Design-Build project delivery method combines all or some portions of the design and construction phases of a project - including design, regulatory permit approvals, utility relocation, and construction – into a single contract.
The following is a reflection of various aspects of the project phases as they have occurred or will occur for the proposed US 64 bridge replacement.

Timeline for Design-Build Project Delivery Method
On November 18, 2019, TDOT awarded the contract the US 64 project to Charles Blalock & Sons, Inc. for $12.6 million. The work will be completed in less than two years using traditional construction.
TDOT and the Design-Build team will work to finalize the design and project clearance to allow construction to begin as early as summer 2020. The initial schedule of work is as follows.
- Phase 1
- construction of new bridge on new alignment
- construction of roadway approaches and side road tie-ins
- Phase 2
- reconstruction of Welcome Valley Road and Hildabrand Road at tie-in locations
- shift traffic to new bridge
- remove approaches on existing US 64
- Phase 3
- final paving, signing, and striping
- remove old bridge
- construction of maintenance road (old US 64)
Two travel lanes will remain open at all times during construction, with the exception of short-term lane closures needed to demolish the old bridge and set beams for the new bridge. Traffic will be flagged as needed for any temporary lane closures. No lane closures will be allowed on any day water is released from the Ocoee River Dam 2.
Because US 64 will remain open for the duration of construction, no detours will be set up.
The river will be open to all traffic (tube, canoes, etc) during rafting season (March 1 – Labor Day).
