ORIGINAL RELEASE:Knife River construction, under contract to the City of Idaho Falls, will be replacing the structure that carries 17th Street over the Moody Canal immediately east of St. Clair Road. To facilitate the construction, full nighttime closures of 17th Street between St. Clair Road and Woodruff Avenue will take place each night beginning on Tuesday, March 14. Up to one lane of traffic on 17th Street in each direction will close at approximately 7:00 p.m., followed by full closure of the roadway at 11:00 p.m. The roadway will re-open to traffic each morning by 5:00 a.m., with single-lane closures extending into the mid-morning hours as necessary. Traffic on 17th Street between St. Clair Road and Woodruff Avenue will be detoured north to 12th Street during the nighttime full closures. Barring unforeseen conditions, the project should be completed by the end of the week. Please watch for equipment and workers, follow all traffic signs and flaggers, and reduce speeds to posted limits. 

Beginning March 1, 2017, Knife River will commence construction work on 17th Street at the St. Clair Road intersection. In an effort to reduce the impact to traffic, the intersection will remain open for the duration of the project with possible night closures. The project includes construction of approximately 900 feet of pipeline to replace the canal along the east side of St. Clair Road. Work will begin just south of the Big Lots store south of 17th Street, continue through the intersection, and at 17th Street, and end just north of Great Harvest Bread north of 17th Street. This work is being completed to accommodate a future roadway widening project to add turn lanes on St. Clair Road at its intersection with 17th Street. Construction hours will be from 7:00 a.m. to 6:00 p.m., Monday through Friday. The duration of the project is approximately one month. For questions or concerns, contact Knife River at (208) 941-8278 or the Public Works Department at (208) 612-8250. Please watch for equipment and workers, follow all traffic signs and flaggers, and reduce speeds to posted limits.
