Along this project route the interstate road surface is deteriorating and needs to be replaced. The resurfacing work will eliminate rough sections and soft spots in the road. As a part of this project, ITD will also upgrade the guardrail on I-15. Through a method called Cold-in-Place Recycling, ITD will re-use the old pavement in the new roadway. This method reduces waste and lowers costs.
