County Road 5 Traffic Flow Improvement Project Scheduled to Begin August 17

Larimer County Road 5 Detour Map

Starting August 17, roadwork is scheduled to begin on Larimer County Road 5 (LCR 5) near Highway 392. These road updates are designed to improve traffic flow along LCR 5 in areas currently susceptible to regular traffic congestion.

The project will service LCR 5 by increasing road capacity to two lanes in each direction, constructing two multi-lane roundabouts at congested intersections and adding new dedicated bike lanes. The town will also install additional infrastructure such as water and sewer piping that will serve local residents.

During the project, LCR 5 will be closed between Larimer County Road 32E (LCR 32E) and Highway 392. Access to LCR 5 by way of Oakmont Drive in the Ptarmigan subdivision will also be closed. LCR 32E (Jacoby Road) will be closed to through traffic west of Larimer County Road 3. Detours will be posted and the commuting public will be encouraged to follow alternative routes. Prior to the LCR 5 closure, a new section of Westgate Drive that is currently under construction will be completed and will serve as a bypass road for traffic to detour around the LCR5 closure. The new connection will extend from its current location to LCR 5 at LCR 32E. Ptarmigan residents will retain access to Highway 392 by way of Highland Meadows Parkway. East access to Ptarmigan by way of LCR 3 will remain open as well.

For this project, two multi-lane roundabouts will be constructed on LCR 5: one located at Oakmont Drive and LCR 5 and the other located at the intersection of LCR 5 and LCR 32E. Roundabouts allow for a constant flow of traffic through busy intersections. According to the Federal Highway Administration, roundabouts cost less to maintain compared to an average stoplight and there are shorter wait times due to vehicles yielding at intersections instead of waiting at stoplights. There are also eight points of conflict in a roundabout compared to the 32 points of conflict found in a stoplight intersection, which reduces the risk of serious traffic accidents.

The project is weather permitting and will result in a long-term road closure. It is expected to be completed before Thanksgiving 2020. Crews will be working weekend shifts, in addition to weekdays to keep the project on schedule. Project updates will be shared as they become available.
