Highway 9 bridge closure in Frisco begins Monday

The Colorado Department of Transportation begins the construction of upgrades on the Highway 9 bridge Monday at 10 p.m. over Interstate 70, requiring an around-the-clock closure to all traffic and major detours for vendors.

“We have been passing out flyers to local businesses alerting them about this closure so that they can notify their vendors,” said Brodie Boilard, spokeswoman for the town of Frisco. “This is kind of a major closure – trucks that weight more than 10,000 pounds will have to detour around Summit Boulevard.”

Construction continues through Sept. 27, with the bridge and Exit 203 closed from 10 p.m. to midnight Mondays through Thursdays. The construction work consists of removing old expansion joints and installing new ones.

“Those expansion joints are deteriorating and need to be replaced before winter returns,” said Steve Alderman, CDOT Region 1 bridge coordinator. “The new joints will tolerate temperature changes much better and smooth out the bumps, allowing for better snow and ice removal and ultimately, improving traveler safety.”

The bridge will remain open Friday mornings through Monday night to accommodate weekend traffic.

While the closure is in place, all ramps remain open, providing access between eastbound I-70 and Frisco. The westbound ramps also will be open, allowing residents on the north side of the interchange to exit or enter I-70.

All large trucks weighing more than 10,000 pounds will need to use Hwy. 9, Summit Boulevard, to access eastbound I-70. Westbound truck traffic will need to go east on I-70 to the Silverthorne Interchange Exit 205 and turnaround to access westbound I-70.

Expansion joints allow bridges to expand and contract, and avoid structural damage. Replacing the joints periodically can extend the service life of a bridge several years, Alderman said.
