A / The bridges along I-59/20 and portions of I-65 through Birmingham’s Central Business District (CBD) were constructed over 45 years ago and were originally designed to accommodate 80,000 vehicles per day. Today, this stretch of Interstate has the highest rate of traffic flow in Alabama, carrying over twice the number of vehicles than it was intended to accommodate. By 2035, this number is expected to increase to over 225,000 vehicles per day. Consequently, this vital infrastructure is functionally obsolete, and must be replaced in the interest of public safety and to ease the flow of commerce and traffic through Birmingham’s CBD.
A /Work on Phase I began in September 2015 and was completed in the Fall of 2016. Much of that work involved the widening of some roads and elevating of some bridges in the interchange of I-59/20 with I-65. Phase II, which involved redesigning and constructing the new interchange ramps at I-65, was completed in late 2018. Work on Phase III involves the replacement of bridges at the interchange between I-59/20 and Red Mountain Expressway, or U.S. 31 and U.S. 280, and the bridges that carry I-59/20 through downtown. The project is expected to be completed by the end of the 2020 calendar year.
