Eastbound US 36 Rebuild Project Update

August 23, 2019

US 36 Re-Construction Update: The Eastbound US 36 Emergency Rebuild Project is moving into the rebuild phase of the half-mile stretch of eastbound US 36 between Wadsworth Boulevard and 104th/Church Ranch Boulevard.

The No. 1 priority for CDOT and Kraemer North America has been to return eastbound US 36 to its original traffic pattern with three lanes in each direction. This – along with a temporary bike path – is expected in October. Additional work on the wall, final bike path, and fence is expected to last through December.

There continues to be no movement on the westbound side. It is stable and safe for traffic. Some overnight lane closures are anticipated, but impacts to traffic are expected to be minimal during reconstruction. Two travel lanes remain open in each direction on the westbound side during daytime hours.

US 36 Bikeway Update: Due to the damage to US 36 between Wadsworth Boulevard and Church Ranch Boulevard, the US 36 Bikeway surrounding that area has been indefinitely closed due to safety concerns and construction. CDOT, along with the cities of Broomfield and Westminster have determined this route to be the safest detour option during this time.

Please note there are no bike lanes but there are 8’ continuous sidewalks on the east and west sides of Westminster Blvd between 112th Ave and Promenade Dr. Please watch for driveway accesses if using sidewalks. Bike lanes and shoulders are inconsistent on 112th Ave. between Westminster Blvd and Parkland St. Bicycles may legally take the lane if there are no ridable shoulders or to avoid hazards.

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.
