Along this project route the interstate road surface was deteriorating and needed to be replaced. The work eliminated rough sections and soft spots on the road. ITD also upgraded the guardrail on I-15. Through a method called Cold-in-Place Recycling, ITD reused the old pavement in the new roadway. This method helped to reduce waste and lower costs.
