| Abstract | The total project road length is about 1.35 miles in the City of St. Paul, Minnesota. The project was proposed to improve safety and reduce congestion by increasing roadway capacity, provide a smoother ride, improve drainage in the areas, and extend the service life of the roadway, bridges and drainage system. Figure 2 shows an overview of the project area. Specifically, the preferred Build Alternative identified in the Environmental Assessment: Extends the existing auxiliary lane on the right side of eastbound I-94, from its starting point at the Jackson Street entrance, to Trunk Highway (TH) 52 (east of its current terminus at the East 7th Street exit); Retains the existing auxiliary lane between the left entrance of Broadway Street and the left exit to Mounds Boulevard; Constructs a new auxiliary lane on eastbound I-94 beginning at the entrance from southbound I-35E, tying into the five lanes at Mounds Boulevard; Constructs two emergency pull-out areas, with one between TH 52 and Kellogg Boulevard, and another between Kellogg Boulevard and Maria Avenue; Removes old lane markings with diamond grinding in area where travel lanes must cross concrete joints; Reduces the Mounds Boulevard entrance onto I-94 from two lanes to one; Adds water treatment areas; Proposes two noise barriers; and Removes bus shoulder lanes |
