Silver Plume Sound Wall & Drainage Project underway next week

September 19, 2019 - On-ramp to be closed eight weeks

SILVER PLUME — The Colorado Department of Transportation begins replacing the sound wall along westbound Interstate 70 and westbound on-ramp in Silver Plume on Monday, Sept. 23. 

Work hours are from 7 a.m. to 5 p.m., Monday through Friday.  Construction includes replacing the existing, deteriorating sound wall with new concrete and steel posts that will improve safety, functionality, durability and aesthetics.  Storm drainage also will be upgraded in this area.

To safely demolish the current sound wall and provide ample room for construction equipment, CDOT will close the on-ramp from Silver Plume to westbound I-70 for eight weeks, beginning on Thursday, Sept. 26, and continuing through Tuesday, Nov. 19.  The detour route to access westbound I-70 while the ramp is closed is west on Water Street/Silver Valley Road about five miles to the I-70/Bakerville Interchange. 

Minor delays can be expected while flaggers are directing traffic on Water Street during drainage system construction.


  • Sept. 26 to Nov. 19: Complete closure of on-ramp from Silver Plume to westbound I-70
  • Nov. 20 to March 31, 2020: Ramp reopens to traffic.  Limited construction may take place outside active traffic as winter conditions allow
  • April 1, 2020 to June 2020: Construction and complete ramp closure resumes

The $3.2 million project, contracted to Lobato Construction of Westminster, is scheduled for completion in June 2020.

To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project takes a systematic statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.



CDOT has approximately 3,000 employees located throughout Colorado, and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
