In 1977, ALDOT publicly unveiled the final routing of the route and presented it at a series of public meetings in August 1977. The selected route resulted in the slight relocation of 35th Street, the construction of a bridge along 31st Street over the freeway and the construction of a continuous viaduct along the final leg of the freeway through its 15th Street junction. Plans were also unveiled to add an additional travel lane in each direction along I-20/59 between its junction with I-359 and McFarland Boulevard.
