The City of Twin Falls will close Martin Street at Filer Avenue starting Feb. 19 to continue essential infrastructure work to prepare for a new roundabout at the intersection of Wendell Street, Martin Street and Filer Avenue. Filer Avenue will also remain closed while crews complete the installation of the irrigation line in that area.
Work to improve the irrigation system started on Feb. 2 and has included the extended closure of Filer Avenue to install new irrigation pipe. While the roundabout itself is slated for construction later this spring, crews must first modernize the area’s canal and irrigation piping. This phased approach mirrors successful recent projects on Eastland Drive, ensuring that underground utility work is completed before road surfacing begins.
Traffic Impacts and Road ClosuresTo facilitate the installation of a new lateral pipe across Filer Avenue, the following closures will be in effect: Martin Street Closure: Closed to traffic at Filer Avenue starting Feb. 19. Duration: This specific crossing is expected to take two weeks, with the road scheduled to reopen on March 5. Overall Project Timeline: While the Filer Avenue crossing is short-term, the total irrigation piping project will continue through March 20. Residents should expect periodic closures on Wendell and Martin Streets during this window. | Why a Roundabout?The intersection of Wendell, Martin, and Filer Avenue is currently a complex "Double T" configuration that struggles to handle modern traffic volumes. Recent data highlights the urgency of the upgrade: High Volume: Nearly 8,000 vehicles daily navigate this specific stretch of Filer Avenue. Complexity: The "Double T" layout creates multiple conflict points, making it difficult for drivers to maneuver safely as northwest Twin Falls grows. Comparison: For context, the high-traffic area of Eastland Drive in front of O’Leary Middle School sees approximately 11,000 vehicles per day. |
By installing a roundabout, the City aims to simplify these movements, reduce wait times, and significantly improve safety for the thousands of motorists who rely on this corridor every day.
Note to Residents: Please follow all posted detour signs and exercise caution near construction zones. We appreciate your patience as we make these necessary improvements to our city’s infrastructure.
