Overview

• The restriction begins Sept. 22 on SR-39, barring vehicles and loads longer than 50 feet from the Ogden Canyon corridor.
• The speed limit in The Narrows will drop to 35 mph, and radar speed feedback signs will be installed to curb speeding.
• UDOT engineers modeled large-truck movements and found that vehicles exceeding 50 feet would encroach on oncoming traffic in segments including The Narrows.
• Officials note five traffic deaths along the route since 2015 and say the new steps build on 2024 measures such as rockfall mitigation, barrier replacement, rumble strips, and added warning signs.
• UDOT’s Mitch Shaw calls the move an essential safety action and urges drivers to slow down and avoid distractions, and KSL reports Utah Highway Patrol and the Weber County Sheriff’s Office will enforce the rule.
