Drivers will see delays and road closures across the state the week of August 19, as the USA Pro Challenge, one of the biggest road bike races in the country, pedals through the High Country.
Transportation officials warn that the more than 1 million spectators expected to attend the event and closures to accommodate the teams could cause heavy traffic volumes on highways.
In Summit County, Highway 9 north over Hoosier Pass to Breckenridge will be impacted from 7 a.m. to 4 p.m. Aug. 20 and north to Kremmling from 10 a.m. to 4 p.m. on Aug. 21 as the bike race moves through the area.
Competitors will complete Stage 2 of the race in Breckenridge the afternoon of Aug. 20 and leave the following morning bound for Steamboat Springs for Stage 3.
Transportation officials say to the extent possible, closures will be kept to a minimum and highways will be reopened as quickly as possible after teams leave an area, but drivers are still encouraged to plan their trips in advance — whether they are planning to watch the race or not.
Daily road closure information will be made available online at CoTrip.org or by phone by calling 511. Drivers can also receive real-time information on highway delays and closures related to the race by signing up for email and text alerts from CDOT at Coloradodot.info.
