Western Rock

Project location: I-15; MP 37 — M 44, Add NB Climbing Lane

This project involved reconstruction of the I-15 southbound curve at Blackridge to change the abrupt curve at MP 37. A cast-in-place barrier was placed in the median of this curve, replacing precast barrier. Project included demolition and reconstruction of the bridges at New Harmony and Kolob Canyon exits, and seven miles of an additional passing lane on the northbound from MP 37 to 44. The traffic pattern changes warranted signing, striping and wildlife crossing improvements.
