The Wyoming Department of Transportation (WYDOT) issued a notice that a portion of Interstate 25 in Casper will be closed overnight on Saturday, Sept. 26, to keep sewer‑system upgrades moving forward. The closure runs from 7 p.m. Saturday until 4 p.m. Sunday, Sept. 27, covering the stretch between mileposts 186 and 187.
Detour routes for motorists
Northbound drivers are instructed to exit at the Beverly Street/Bryan Stock Trail off‑ramp (exit 186). From there, traffic will follow Bryan Stock Trail north to Amoco Road, then re‑enter I‑25 at the Shoshoni Bypass interchange (exit 189). Southbound traffic will also exit at exit 186, but will detour onto Yellowstone Highway before returning to the interstate via the Yellowstone Highway on‑ramp.
Impact on local streets
During the closure, Beverly Street will operate with only one lane in each direction. Southbound interstate traffic will not be able to turn left onto Beverly Street, and northbound traffic will be prohibited from turning right onto the same street. Flaggers and traffic‑control personnel will be on site to guide drivers and ensure safety.
Why the closure matters
The sewer upgrades are part of a larger reconstruction project aimed at improving the reliability of Casper’s water‑treatment infrastructure. By closing the highway overnight, WYDOT can complete the work more quickly and with fewer disruptions to daytime commuters. Residents are urged to follow detour signs, heed flaggers, and plan alternate routes for the brief interruption.
What residents should do
Travelers should allow extra time for the detour and consider using alternate routes such as US‑20 or local streets if possible. The department advises drivers to stay alert for construction signage and to obey all flagger directions. Updates will be posted on the WYDOT website and local news outlets throughout the weekend.
Looking ahead
WYDOT expects the sewer‑upgrade work to continue through the summer months, with additional nighttime closures possible as the project progresses. The agency emphasizes that these temporary inconveniences are essential for maintaining a safe and efficient water‑service system for Casper’s growing population.
