Eastbound US 36 Rebuild Project Update

Oct. 11, 2019

US 36 Re-Construction Update: 

With construction starting in July, the US 36 project was completed sooner than projected. The once collapsed US 36 is now up and back to original configuration, opening all lanes from Wadsworth to Church Ranch Blvd. Express Lanes are running in both directions.

CDOT and Kraemer North America have worked diligently to provide commuters with their normal commute. The use of Geofoam assures commuters that this incident will not happen again in the future.

US 36 Bikeway Update:

A temporary bike lane is open along US 36 between Wadsworth and Church Ranch Blvd. CDOT advises to bike with caution, as the temporary bike lane is near an active construction zone and near US 36 traffic separated by a 3-foot-tall concrete barrier. The final bike path is expected to be done in December.

Please email info@commutingsolutions.org with any questions regarding the US 36 Bikeway during this time.

What is Geofoam?

The rebuilt section of US 36 will include drilling concrete caissons down into the bedrock and placing a material called geofoam behind the retaining wall in place of the existing backfill. Geofoam is a lightweight backfill that has been used effectively in similar situations with settlement. Since geofoam is lightweight, it reduces pressure and stress to the underlying soil. It is also very strong, which means it can safely support highway loading and also lead to improved slope stability. Of the different options considered, this option provides the best factor of safety. The geofoam is being produced by Insulfoam, which has a local plant in Aurora.

Speed Up Your Commute

During the re-construction project on US 36, there will be increased congestion along the corridor. To alleviate congestion issues and reduce your commute time, there are alternatives to driving alone. Using the My Way to Go network, you can connect with carpools or vanpools along the US 36 corridor. Not only will this take cars off the road, its great for your wallet and the environment. Learn more about carpooling here.

Vanpools are a great option for commuters who travel more than 15 miles to work one-way. Passengers share the ride in a vehicle—which, contrary to the name, isn’t always a van— that seats 5-15 people. Participants pay a monthly fee that covers the cost of fuel, insurance and vehicle maintenance. For a limited time, receive $20 a month off the cost of vanpooling through the VanCool program.

US 36 is also home to the Flatiron Flyer, RTD’s first Bus Rapid Transit (BRT) service to connect Boulder to Denver. The Flatiron Flyer offers commuters a reliable ride every 4 to 15 minutes during peak hours and every 15 minutes off-peak, Monday through Friday. 2019 Flatiron Flyer fares: $3.00 local three-hour pass and $5.25 regional three-hour pass.
