Project Milestones
What is the current problem?
The existing box culvert was built in 1936 and is in poor condition. Erosion is occurring on the Route D embankment due to frequent flooding during heavy rain events.
What exactly is being done to address the problem?
The project will replace the existing box culvert with a larger box culvert. The project also includes raising the grade of Route D about 18 inches to reduce the frequency of roadway flooding.
What is the construction impact?
Route D will be closed during construction between Route T and Cappeln-Osage Rd. The signed detour will be Route T north to Route N east to Route Z south and vice versa. New right-of-way and easements will be required.
When is construction expected to begin?
Construction is set to begin in November 2023, with an expected completion date by February 2024.
