US 36 Weekly Update

Weekly Update: Week of Aug. 14

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. 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.  

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.

Weekly Update
July 29, 2019

Over the past weekend (July 26 through July 28), 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 was able to remove all of the concrete pavement from above the wall. Crews will continue to remove the side of the wall throughout the rest of this week.

Meanwhile, the design team is working on plans for a final fix. As of Monday, 60 percent of the design is completed. CDOT and Kraemer are working together toward a goal of 90 percent design by the end of this week. Complete removal of the wall is expected within the next few weeks, and rebuild will begin immediately after that.

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 nights and weekends 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.
