The two project locations include:

  • Park County Site 1 – CO 9 MP 27.77

  • El Paso County Site 2 – CO 115 MP 42.41

The culverts will be rehabilitated using several methods that vary from site to site. Site 1 work includes Slip lining and extension of culvert, place grouted riprap and riprap at outlet. Site 2 work includes spray lining culvert, excavating material, grade ditch slopes, and line ditch with concrete at outlet, place riprap and construct small maintenance access road at outlet. 

The goal of the project is to increase the longevity of each stormwater conveyance pipe to prevent failures and erosion of the embankment(s), while ensuring the safety of the travelling public.

Travel Impacts

Most of the work will occur off the roadways. However, within the construction zone there will be reduced speeds, daily shoulder closures, single lane closures and traffic devices denoting the area. Work will be performed only during daytime hours and may include some Saturday work.

The traveling public is urged to obey signage for detours, speed reductions, and overweight/oversized restrictions. Motorists should also be aware of flaggers, maintenance workers and heavy equipment on and along the roadway.
