Scope of Work:

The primary objective of the projects is to provide bridge rehabilitation for the Old Roosevelt Bridge. The bridge rehabilitation project will include:

  • Replace span locks which connect the two halves of the movable bridge deck when the bridge is in the “down” position
  • Renovate the bridge tender house
  • Filling in open grating with concrete to improve the rideability of the shoulders so bikes can safely stay in the road
  • Improving maintenance access to electrical and mechanical components
  • Bridge painting as needed
  • Miscellaneous repairs to:
    • Fender
    • Sanitary Line
    • Grating Repairs
    • Deck Sealing

Construction Impacts:

  • Work will be done in phases to reduce the effects of construction on the community
  • Full and partial bridge closures will occur only during specific phases and detours will be provided utilizing US-1.
  • Temporary lane closures will be required for some phases (such as minor repaving) and will occur during non-peak hours.
  • Marine vessel traffic will be maintained with temporary closure on half the channel during fender construction.
  • Another public meeting (Construction Open House) will be held prior to construction. Detailed information about how to keep informed of potential construction impacts will be provided at this meeting.
  • Temporary modification to the draw bridge operation schedule will be coordinated with the United States Coast Guard.
