Augusta Bottom Road Bridge

The project involves the replacement of a deficient steel girder bridge on Augusta Bottom Road over a tributary to the Missouri River, located 0.5 miles east of Emke Road. Proposed improvements include:

  • New widener structure to provide for 12-foot lanes and 4-foot shoulders.
  • Realignment to allow old bridge to remain in place while new structure is constructed.

The project is funded by St. Charles County’s ½-cent Transportation Sales Tax and with Federal Highway Administration (FHWA) Surface Transportation Program-Suballocated (STP-S) funding. The project is estimated to cost approximately $730,000.

Current Phase

Design by Great River Engineering began early in 2022. Construction is scheduled for 2024. The consultant has finished field surveys and submitted Conceptual Plans. They have been reviewed and a single span bridge has been approved. Work now begins on preliminary plans which are due in September 2022.
