3650 South /1450 South Road Project

Purpose and Need

This project is part of a regional project between Washington City and the City of St. George. The project will realign 3650 South (Washington City) to line up with 1450 South (St. George) at the signalized intersection at 3000 East.  This will help alleviate conflicting traffic movements at the intersection of 3650 South/1580 South and 3000 East. This roadway will eventually link the Southern Corridor to I-15.
