Project Description:

The Southern Railway crossed Breckinridge Lane to form an at grade intersection. Due to heavy traffic on Breckinridge Lane, the Kentucky Department of Transportation decided to four-lane Breckinridge Lane and take it under the railroad, leaving the railroad grade undisturbed. The railroad requested that the bridge carry two tracks over Breckinridge Lane and that railroad service not be interrupted during construction. While the original track was maintained with sheet piling during excavation, the bridge for the second track was built. Once completed, the rail traffic was diverted to the new track while the bridge was constructed for the original track. The side by side bridges consisted of a single span of 84 feet. The framing was made up by using eleven 75 inch deep welded plate girders with a concrete deck. The abutments were the breastwall type and were founded on rock. Plans were completed in 1977 and construction was completed in 1981. The construction cost of the bridge portion of the project was $750,000.
