Traffic Impacts

Due to the size of the State Route 55 project, the contractor will be conducting construction activities in three phases. Please note that scheduled phases are tentative and dependent on weather and project progress.

PHASE 1 & 1A –January 2024 to June 2024

  • Pedestrian detour will be in place to re-route those using the Rock Creek Greenway during construction of a permanent pedestrian access point from SR 55.

PHASE 1B – June 2024 to March 2025

  • Traffic on SR 55 will be shifted to the west side of existing bridge. Both lanes of traffic on SR 55 will remain active for the duration of the project.
  • Once construction of permanent Rock Creek Greenway pedestrian detour is in place, pedestrians will be re-routed for the duration of North Fork Rock Creek bridge replacement.

PHASE 1C – March 2025 to December 2025

  • Traffic on SR 55 will be shifted to the east side of existing bridge. Both lanes of traffic on SR 55 will remain active for the duration of the project.
  • Permanent Rock Creek Greenway pedestrian detour will remain in place, pedestrians will be re-routed for the duration of North Fork Rock Creek bridge replacement.

PHASE 2 – April 2025 to April 2026

  • Traffic on SR 55 will be shifted to the west side of existing roadway during the construction of new driving lanes on the east side of SR 55. Both lanes of traffic on SR 55 will remain active for the duration of the project.

PHASE 3 –February 2026 to May 2027

  • Traffic on SR 55 will be shifted to the east side of existing roadway during the construction of new driving lanes on the west side of SR 55. Both lanes of traffic on SR 55 will remain active for the duration of the project.
  • Upon completion of new driving lanes, possible temporary lane shifts may be necessary to complete roadway construction activities.

Two historical properties have been identified on the project: the Oakwood Cemetery (Tract 36) and the Coca-Cola building (Tract 33). The proposed impacts to these properties have both been coordinated with the State Historic Preservation Office.
