Modifying and constructing entrance/exit ramps
Constructing/widening the outside mainlanes and frontage roads
Constructing U-turn bridges in both directions at William Cannon and Stassney
Phase II work includes building a new bridge at Stassney

Three mainlanes in each direction with extended entrance/exit lanes for the entire length of the project
