Plum Creek Parkway Widening

Project update

  1. Upcoming Traffic Impacts

    Monday, Nov. 23 through Thursday, Dec. 17, Eaton Street will be closed at the entrance to Plum Creek Parkway. Residents will be directed to a detour on Valley Drive, which can be seen on the detour map. By closing Eaton Street, contactors will be able to complete a significant amount of work, weather dependent.

From Founders Village to Downtown, Plum Creek Parkway is a key roadway that connects motorists to neighborhoods around Town. As part of its Transportation Master Plan, the Town is investing in the widening of Plum Creek Parkway, east of Gilbert Street. 

Project overview

In fall 2019, underground utility work began along Plum Creek Parkway in preparation for improvements to the roadway. Portions of the underground utility work were completed in May 2020, when construction began on the roadway to widen the parkway between Gilbert and Eaton streets and add two roundabouts.

This project will improve traffic flow for Plum Creek Parkway, but in the meantime, motorists are advised to take alternate routes. The Town will maintain access into neighborhood streets throughout construction of the roundabout at Eaton.

As the project progresses, motorists can expect new traffic patterns as the roundabout at Plum Creek Parkway and Eaton Street is constructed. Starting the week of Nov. 16, the project will move into its final phase of construction to complete the new west bound lanes and the northern half of the new roundabout at Eaton Street. Finally, in December the project will begin pavement striping to open the roadway to final configuration. Minor work will continue into spring 2021 to complete seeding and final cleanup.

Additional improvements with this project include a guardrail along parts of westbound Plum Creek Parkway, a new sidewalk, bicycle lanes and flashing crosswalk beacons to improve pedestrian and driver safety. 

Water quality pond on northwest corner of intersection  

The improved roadway down the Plum Creek Parkway corridor will also increase the volume of stormwater runoff during rain events. In many cases, roadways work to help convey water into the stormwater system. In order to help with the water quality draining into Sellers Gulch, a pond has been added to the northwest corner of the intersection of Plum Creek Parkway and South Gilbert Street.


The roadway improvements to widen Plum Creek Parkway, along with completion of roundabout construction at the Gilbert and Eaton intersections is anticipated in late December 2020.


Phase 1B of the project will cost about $6.8 million and is being primarily funded by the Transportation Capital Fund, which receives revenue from development impact fees. The replacement of the existing pavement, which is just under $1 million, will be funded mostly by sales tax revenue from the Transportation Fund. 

Transportation Planning

These improvements were defined in the Town’s Transportation Master Plan. Reducing congestion in the area has been a priority for Town Council. Learn more about that plan and read the document at
