US 36 Weekly Update

Crews are continuing earthwork efforts and finishing touches on the permanent bike path. Due to winter weather through late 2019 and early 2020, final project completion is now expected in spring 2020.

Lane Closures

Crews will close the right lane of eastbound US 36 for one night to install an impact attenuator, which is a device intended to reduce damage to vehicles and motorists in the event of a crash. This work will happen overnight either on Monday, Tuesday or Wednesday, depending on weather. The closure will begin at 8 p.m. and last through 5 a.m. To ensure the safety of bicyclists, crews will also close the temporary bike path. Both the lane and bike path closures are for one night only. 

For the most current information on when this closure is happening, watch overhead message boards along the US 36 corridor. 

This work is weather-dependent and subject to change.

Temporary Bike Path

A temporary bike path is open. Bicyclists should exercise caution while riding on the temporary bike path because it is located near the active construction zone and is in close proximity to US 36 traffic. The temporary bike path is separated from traffic by a three-foot-tall concrete barrier.

Please note during the closure above, the temporary bike path will be closed overnight. The temporary bike path will reopen once the above closure concludes.

This week, crews finished all work on the median barrier and lighting. Crews have also finished all planned lane closures for 2019. The next planned lane closures will be in mid-January. Until then, crews plan to continue earthwork and finishing touches on the permanent bike path.

Due to extreme winter weather during October, November and December, final project completion is now expected in January 2020.

There are no planned lane closures through the rest of December and most of January. Email updates will begin again when there are planned travel impacts.

For any additional information, please check the website (www.codot.gov/projects/eb-us-36-emergencyrepairs). Have a safe and happy holiday season!

Schedule Change Due to Weather

Due to the precipitation expected overnight Tuesday, Oct. 1, the decision has been made to push back the US 36 traffic switch one day. The overnight lane closures will now take place on Wednesday and Thursday nights, Oct. 2 and 3. This decision was made because the project needs to have dry pavement conditions in order to safely and effectively stripe the roadway.

By Friday morning’s commute (Oct. 4), crews anticipate having US 36 back into its original three-lane configuration with Express Lanes open and operational at that time. The following activities are expected to restore US 36 lanes back into its original configuration. Remember: work is weather-dependent.

Lane Closures

• 8 p.m. Wednesday, Oct. 2, through 5 a.m. Thursday, Oct. 3
  • Single-lane closure of both eastbound and westbound US 36 so crews can restripe and move barrier
• 8 p.m. Thursday, Oct. 3, through 5 a.m. Friday, Oct. 4
  • Single-lane closure of both eastbound and westbound US 36 so crews can finish restriping the roadway into its original configuration and reset median barrier.

Traffic Changes

In addition to the above lane closures, motorists can expect the following traffic changes:

• Thursday morning at 5 a.m.
  • Two eastbound lanes of US 36 will be restored to its original configuration.
  • The bike path will be opened into a temporary configuration shortly after.
• Friday morning at 5 a.m.
  • All lanes of US 36, both eastbound and westbound, will be opened in their original configuration.
  • Express Lane tolling will begin at 5 a.m. in both directions.

Ongoing Work

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 is expected in full by the morning commute on Friday, Oct. 4.

Additional work on the wall, final bike path, and fence are expected to last through December. This includes:

• Reconstruction of median barrier and lighting (this will require nighttime lane closures)
• Installation of concrete caissons, which will be drilled down to bedrock to ensure stability of the wall. This work will be completed this week.
• Placement of 77 wall panels that form the façade of the retaining wall.
• Final bike path configuration and fence barrier separation from the highway.

With the geofoam, load distribution slab, and concrete pavement in place, three lanes of eastbound US 36 can be safely opened while the remaining work on the wall is on-going.

Temporary Bike Path

Crews plan to re-open the bike path into a temporary configuration by Thursday morning, Oct. 3.

Bicyclists should exercise caution while riding through this area because the temporary bike path is located near the active construction zone and is in close proximity to US 36 traffic, separated by three feet tall concrete barrier.

Once the temporary bike path is open, bicyclists can expect intermittent closures of the bike path through November so construction crews can continue to safely work on the side of the wall.

Crews have been working hard to rebuild the eastbound US 36 wall and achieved a major milestone this week. Geofoam installation is complete – all 6,000 blocks have been placed. Crews continue installing concrete caissons, which will be drilled down to bedrock to ensure stability of the wall foundation. Approximately 70 of the 141 concrete caissons have been drilled so far.

By Friday, Sept. 20, crews will complete the final load distribution slab pour. Crews are expected to start pouring the concrete pavement for the roadway itself next week.

Crews are still on track to open the eastbound US 36 lanes by early October.

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.

Construction Timeframe

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 is expected in October. In addition to opening traffic to the original alignment, crews will install a temporary bike path that will open to the public in October. Additional work on the wall, final bike path, and fence is expected to last through December.

The project team is working around-the-clock to restore the road to its original configuration.

Speed Up Your Commute

During the rebuild 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, it’s great for your wallet and the environment. Learn more about carpooling.

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 local three-hour pass and $5.25 regional three-hour pass.

Crews have been working around-the-clock to rebuild the eastbound US 36 wall. Geofoam installation continues, and approximately 4,500 geofoam blocks have been placed. More than 6,000 blocks of geofoam are expected to be used during this rebuild project. Crews have also started installing concrete caissons, which will be drilled down to bedrock to ensure stability of the wall foundation. Approximately 50 of the 141 concrete caissons have been drilled so far.

Crews have also begun tying rebar on the load distribution slab and have completed the first pour. This concrete slab will distribute weight evenly along the geofoam blocks.

CDOT and its contractor partner, Kraemer North America, have been hard at work since the middle of last week rebuilding the eastbound US 36 wall. Over the weekend, crews completed the rock foundation underneath the wall. Now, geofoam installation is underway. More than 6,000 blocks of geofoam are expected to be used during this rebuild project.

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.

Construction Timeframe

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.

Alternate Routes Available

• Colorado Highway 128 (120th Avenue)
• Colorado Highway 7
• Colorado Highway 93 from Golden to Boulder
• Northwest Parkway (please note, this route is tolled)

Site Surveys

Out of an abundance of caution, the survey team continues to periodically monitor the site. The damage continues to be isolated to one area. There continues to be no movement on the westbound side. It is stable and safe for traffic.

Crews will be working seven days a week to complete repairs safely and swiftly. Two travel lanes remain open in each direction on the westbound side during daytime hours.

The site is being monitored at all times to ensure continued safety for the traveling public.

Over the past weekend, CDOT and its contractor partner, Kraemer North America, made significant progress in the removal of portions of the eastbound US 36 wall. Crews finished removing the wall today and will begin rebuilding the wall immediately. Today, Wednesday, Aug. 14, crews will install a 24-inch storm sewer pipe and backfill this area to construct a strong foundation for the rebuild.

Geofoam Deliveries

The rebuilt section of US 36 will include drilling 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.

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.

Trucks have actively been delivering geofoam blocks since last week. Work to install the geofoam is estimated to begin Monday, Aug. 19.

To date, 1,226 blocks of geofoam have been delivered. An estimated 6,700 blocks of geofoam are expected to be used during the rebuild of US 36.

Site surveys are ongoing

Out of an abundance of caution, the survey team continues to monitor the damaged section of roadway. The damage is isolated to one area, and surveys have shown that the damaged section has settled. There continues to be no movement on the westbound side. It is stable and safe for traffic.

Crews will be working seven days a week to complete repairs safely and swiftly. 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.

The site is being monitored at all times to ensure continued safety for the traveling public.

During this construction, safety is of utmost importance.

Over the past weekend, CDOT and its contractor partner, Kraemer North America, made significant progress in the removal of portions of the eastbound US 36 wall. Working from top to bottom, the team has removed 75% of the wall. Crews will continue removal throughout the rest of this week and weekend.

Once the wall is safely removed, crews will then begin to remove four feet of dirt below the wall and replace it with better material. Then, crews will start to rebuild the wall.

Overnight single lane closures tonight, Tuesday and Wednesday

Drivers who travel US 36 between Westminster and Boulder can expect delays overnight Monday, Aug. 5, Tuesday, Aug. 6, and Wednesday, Aug. 7, as crews install glare screen on the temporary concrete barrier used to shift traffic for the Eastbound US 36 Emergency Rebuild Project.

To enhance safety for the traveling public in this construction zone, crews will now install green slats, called glare screen, on top of the concrete barrier used to separate traffic. This will help to reduce headlight glare and increase nighttime visibility for drivers along the corridor.

To safely complete this work, crews will close the left lanes of both eastbound and westbound US 36 in the half-mile construction zone between Wadsworth Boulevard and 104th Avenue. The lane closures are expected from 10 p.m. to 5 a.m. Monday, Aug. 5, Tuesday, Aug. 6, and Wednesday, Aug. 7. Drivers will still have one lane for travel but should expect minor delays.
