Salem Avenue (SR 49) Phase 1, Roadway & Bridge Deck Rehabilitation

Project Overview

The Salem Avenue (SR 49) Phase 1 project involved the widening and reconstruction of a one-mile stretch of State Route 49, including a 4-lane superelevated roadway and a 3-span reinforced concrete continuous slab bridge (MOT-49-0548). The project aimed to enhance roadway safety, improve traffic flow, and rehabilitate the bridge structure.
