Atbandoncd/01d U.S. 90 - Mississippi htlp://ww\v.aaroads.com/]osthwys/us-90_ms/indcx.html Abandoned/Old U.S. 90 - Mississippi West of Bay St. Louis, U.S. 90 follows a divided 4 lane highway between the city and MS 607. From MS 607 west to the Louisiana State line, U.S. 90 is 2 lanes while travelling through relatively undeveloped bayou. MS 607 however, retains the 4 lanes through to it's junction with Interstate 10. Throughout a good portion of the stretch of U.S. 90 aforementioned, a 2 lane road parallels. This roadway, which is old U.S. 90, acts as a frontage road to modern U.S. 90. A few homes and small business dot the sections of the highway along this stretch. However, one cannot travel the entire stretch without impedement, as some sections are permenantly closed. When this occurs, traffic is diverted back to modern U.S. 90 to avoid the closed section. I encountered this crossing while heading to New Orleans about midway between Bay St. Louis and MS 607.1 turned onto old highway 90 to the west of the span and took these photos during early November of 1999.
