The Utah Department of Transportation, in coordination with Cedar City, began the South Cedar Interchange reconstruction in early March 2014. Workers are reconstructing Cross Hollow Road and reconfiguring the I-15 interchange to a diverging diamond interchange (DDI). These improvements will accommodate future travel demand and improve safety. The new DDI will open in August 2014.
A diverging diamond interchange briefly channels traffic to the opposite side of the road to provide easier and safer access on and off the freeway. This configuration reduces the number of traffic signal phases, which allows traffic to proceed through the interchange more efficiently without increasing the number of lanes.
Construction began on Monday, March 3, on Cross Hollow Road. The project will be phased to reduce impacts. Phase 1 will include the construction of the south side of Cross Hollow Road, the new northbound off-ramp and the southbound on-ramp. Phase 2, anticipated to begin in mid-summer, will include the construction of the north side of Cross Hollow Road, the northbound on-ramp and the southbound off-ramp. Lane restrictions will be in place during construction on both I-15 and Cross Hollow Road. Restrictions on I-15 will take place Monday through Friday. Restrictions on Cross Hollow Road will be continuous throughout the duration of the project; however, one lane in each direction will be maintained at all times. Delays are anticipated on Cross Hollow Road during peak hours; consider using an alternate route. One full weekend closure is anticipated for late summer on Cross Hollow Road to accommodate the opening of the DDI.
