Phase 2 of US 36 Reconstruction - Resident Passes Available Starting Sunday

July 18, 2014 - Northeastern Colorado/CDOT Region 4 - Closure to begin July 29; open for weekend of Aug. 2-3.

BOULDER AND LARIMER COUNTIES — Phase 2 of the US 36 permanent reconstruction project will involve closing the road to thru traffic July 29 – Aug. 9. The road will open for the weekend to all traffic Aug. 2-4.

Only local residents and businesses will be allowed past the checkpoints during the closure. Those residents are on Apple Valley Road, CR 71, Pinewood Springs, CR 80 (Longmont Dam Rd), Big Elk Meadows (CR 47), or residents along US 36 from milemarker 4 to 20.

Below is the schedule for getting passes to enter the area:


  • Sunday, July 20, 8 a.m. to 1 p.m. at the Pinewood Springs Fire Department,61 Kiowa Road.
  • Tuesday, July 22, 3-8 the Boulder County Sheriff’s Lyons Substation, 432 5th Ave.
  • Wednesday, July 23, 3-8 p.m. at the Lyons Substation.
  • Thursday, July 24, 7 a.m. to noon at the Lyons Substation.
  • Saturday, July 26, 8 a.m. to 1 p.m. at the Pinewood Springs Fire Department.


Boulder County Sheriff Office
Passes will also be available at the Sheriff’s Office Headquarters, 5600 Flatiron Parkway, Boulder. Please call the administrative assistant before stopping by the office to confirm she is available. 303-441-4894.

Three documents are needed in order to receive a pass: 
1) valid driver’s license, 
2) a valid vehicle registration 
3) an official document showing the physical property’s address (bill, deed, etc.)

During the closures, Apple Valley Road will be used as the detour for local residents and businesses only.

Other traffic will need to go on SH 7 or US 34 during this closure.

The reason for the closure is to build up the road embankment height and raise the road anywhere from 2 to 10 feet, depending on the location. This will require a lot of machinery and unsafe elevations will exist that are not conducive to accommodating traffic.

US 36 is the first permanent reconstruction project to be tackled after the devastating floods of September 2013. This approach has included shifting the roadway away from the river channel 5 to 50 feet (an average of 20 feet) by removing portion of existing mountainside (approximately 250,000 cubic yards).

Once complete, the improved stretches of roadway will be 12-foot lanes with 6-foot shoulders. Pre-flood, there were 12-foot lanes with minimal shoulders. Not only will the additional shoulders help widen the highway, but the shoulders will also help improve safety by providing space for emergency pull-offs and making it safer for bicyclists. Furthermore, by softening some of the mountain curves, sight distance will be improved along several of the more severe curves on US 36, including Dead Man’s Curve and the approach to Longmont Dam Road.
