Walsh Construction was awarded a series of contracts totaling more than $500M to reconstruct the Expressway. Work began in the summer of 2003 with the reconstruction of bridges and ramps. Damaged retaining walls were reinforced and key frontage roads were reconstructed. Work included the removal and replacement of over 400,000 SY of concrete pavement. Also included was the construction of sewers and drainage systems, new concrete barrier walls, signage, and landscaping.
