UDOT will begin constructing a Truck Escape Ramp on the downgrade section of US-89 in Logan Canyon on Monday, April 20. This project is a high priority for UDOT after four semi-trucks lost control of their brakes in the canyon and crashed near the intersection at Raspberry Square.
The truck escape ramp will be installed approximately one mile west of that intersection and will use an innovative design with a concrete chute to guide the runaway trucks into the right position where cable restraints will then be used to stop the trucks. When the trucks hit the cables, the cables will wrap around the vehicle causing it to lose speed and stop.
The ramp is only one of the measures put in place on to improved safety for trucks travelling through the corridor. Other improvements include a mandatory break check area near the top of the grade, signage and markings explaining details of corridor such as length and grade, and advances notice signs detailing distance to the upcoming truck ramp.
Crews will be working Monday through Saturday from 7 a.m. to 5 p.m., with one lane of traffic open in each direction at all times. Construction expected to be completed in August.
