US 40 & Downhill Drive Intersection Improvements

About the Project

This is an intersection improvement project at US 40 and Downhill Drive on the west end of Steamboat Springs. The work includes aligning Riverside Drive and Downhill Drive to make a more gradual entry from Downhill Drive onto US 40.

Utility work includes:

  • A sanitary sewer extension across US 40
  • Storm sewer improvements and a water main line connection
  • Utility, striping work and installing traffic signal poles and mast arms on US 40 
  • An extension of the sidewalk on the west side of Downhill Drive - this will tie into the existing sidewalk to the north of US 40
  • Crosswalks addition for improved pedestrian safety with the addition of the signal
  • Additional bus stops on the north and south side of US 40
