CDOT begins safety-improvement project, adding passing lane on CO 145 north of Telluride


SAN MIGUEL COUNTY - The Colorado Department of Transportation and contractor Oldcastle SW Group, Inc., will begin a project next week on CO Highway 145 just northwest (up-valley) of Telluride. The work, starting on Monday, April 15, 2019, will greatly improve safety for motorists by widening the two-lane highway, adding a southbound, uphill passing lane (towards Telluride) and improving shoulders between mile point (MP) 73.9 at lllium Road (County Road 65L) and MP 75.1 at Deep Creek Road. Passing lanes will provide space and opportunities for faster vehicles to safely pass slower moving traffic. This safety-improvement project was contracted to Oldcastle for $5.4 million. 

Crews will excavate the hillside along the northbound lane and widen the roadway to accommodate the new southbound passing lane. The work will involve the following:

  • Construction of a reinforced soil slope and rockery retaining wall
  • Installation of new guardrail
  • Replacement of existing culverts at eight locations across this stretch of improvement from Illium Road to the CDOT Maintenance facility
  • Construction of a concrete box culvert at Deep Creek
  • Super-elevation and crown improvements on the roadway (meaning the roadway’s banked curve will be adjusted and its height will be leveled to improve safety for motorists, by way of cornering ease and increased sight distance).


TRAVEL IMPACTS

Through the project’s completion in early December, 2019, motorists can expect some single-lane, alternating travel through the work zone, as well as periods of two-way traffic with narrowed, 10-foot lanes.
