Planned Changes

As part of Longmont’s effort to enhance access to multimodal transportation throughout the city, Longmont plans to implement a “road diet” on South Sunset Street from Creekside Drive to Nelson Road. When implemented well, road diets improve access to multimodal transportation without a significant impact to existing traffic operations. South Sunset Street currently has two travel lanes in each direction and no bike lanes. Using road restriping, the number of travel lanes will be reduced to one in each direction along with the addition of a two-way center left-turn lane and bike lanes. These changes will improve both pedestrian safety by increasing the distance between the sidewalk and traffic, and driver safety by reducing the number of conflict points.

In addition to the changes above, a dedicated northbound right-turn lane will be added to the southern entrance to Sunset Middle School to mitigate the queuing in the travel lane that occurs during pick up and drop off hours.

Traffic along South Sunset Street will be maintained throughout the duration of the project, however, affected parties can expect minor traffic delays and temporary lane shifts during construction hours (7 a.m. to 6 p.m.)


Implementation of these changes will be phased over the next couple years. The first phase will be constructed alongside the asphalt and concrete rehabilitation of South Sunset Street from Lefthand Drive to Ken Pratt Boulevard. A letter providing details on what to expect with asphalt and concrete rehabilitation was sent to affected properties earlier this year. This portion of the project is scheduled to begin in early June and expected to be completed by mid-August. The remaining phases of the project (Creekside Drive to Lefthand Drive & Ken Pratt Boulevard to Nelson Road) are scheduled to begin in late 2019 and spring/summer 2020, respectively.
