CDOT advises of incoming traffic impacts caused by Exit 203 project

The Colorado Department of Transportation and contractor Zak Dirt are continuing work on the Interstate 70 and Exit 203 Interchange Project in Frisco. Work will go through the fall of 2027 with a planned winter hiatus. In the week starting Sunday, May 31, work will focus on two primary objectives — laying the foundations for the new bridge and beginning relocation efforts of Frisco’s main sanitary sewer line. A new line will be installed to support the upgraded infrastructure, which means retiring the old line when it is completed, according to a CDOT newsletter.

Motorists can expect the following impacts while the sanitary sewer work is ongoing, according to CDOT:

• The northbound Colorado Highway 9 right turn-lane will be closed onto Dillon Dam Road, but vehicles will still be able to make the turn using the right through-lane. The closure is expected to last for 10 working days.
• The entrance into Starbucks/Natural Grocers will also be closed from Saturday, May 30, through Thursday, June 4. A detour is in place using the street prior to the entrance — Lakepoint Drive and N. Ten Mile Road — and entering through the back parking lot.
• The pedestrian/bicycle path between Colorado Highway 9 and Dillon Dam Road (east side) will be closed and pedestrians are asked to use the same detour as motorists.  

Daytime work is expected to last from 9 a.m. to 2 p.m., while nighttime work will last from 7 p.m. to 7 a.m. The project aims to reduce traffic congestion, enhance safety features and add bicycle and pedestrian connections along Colorado Highway 9, Lusher Court and Dillon Dam Road at the north end of Frisco — an area that has long experienced heavy backups during peak travel times.
