First designed and built in the early 1960’s, the Dan Ryan Expressway is the busiest expressway in the Chicago area. Accommodating over 300,000 vehicles per day, it is the city's major transportation artery from downtown through the city's South Side. 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. During construction, Northbound and Southbound express lanes were closed for four miles and Walsh Construction crews began working around the clock to replace them. Work includes the removal and replacement of over 400,000 square yards of concrete pavement. Also included is the construction of sewers and drainage systems, new concrete barrier walls, signage, and landscaping. Walsh is fully responsible for developing and implementing the traffic control use.
