Canyon work starts today

Starting today, motorists will be routed into a head-to-head traffic configuration in the eastbound lanes of Interstate 70 in Glenwood Canyon while crews work in the westbound lanes.

The work is expected to continue into October, and the Colorado Department of Transportation says to expect “heavy delays of 30 minutes or longer during daylight work hours.”

Work started in April on Phase 6 of construction on I-70 in Glenwood Canyon from mile marker 117.5 to mile marker 126.5.

The work is to repair and improve more than 20 bridges along I-70. The repairs include bridge joints, removing existing asphalt surfaces and replacing them with polyester concrete surfaces on bridge decks to increase the lifespan of the highway surface, reducing the frequency of repairs. The new surface also functions as a waterproof barrier, preventing corrosion between the concrete and the bridge deck.

The project also includes the construction of a rockfall fence to mitigate the risk of slides. Additionally, more than 3,000 linear feet of bridge rail will be replaced to enhance safety.

The project is scheduled for completion at the end of October.

Among the impacts on travelers beyond significant delays:

• 24-hour single lane closures.

• Reduced and monitored speed limits, from 40 mph to 35 mph.

• A 12-foot width restriction.

• A detour to the Bair Ranch rest area exit for travelers who need direct access to I-70 west.

Some of the old bridge rail on the eastbound lanes is currently being replaced. Individuals using the bike paths may meet trail flaggers who are there to keep them safe in the work areas.
