The Greenville Street Bridge is a bridge replacement project located in LaGrange, Georgia. The new bridge was designed to replace an 81-year old bridge. The original bridge had been closed to traffic for over 2 years before the replacement project began.
One of the biggest challenges for this project was the proximity to two sets of railroad tracks. Excavating for the foundations was one of the challenges because they were within 15 feet of the tracks. Vertical clearance was also restricted over the tracks along with placing a large pre-cast girder over the railroad. All of these things were done all while not interrupting train traffic.
During the demolition of the existing bridge, CWM value engineered the design of two straddle bent structures which resulted in a savings of $855,292 but had no adverse effect on the construction schedule.
The Greenville Street Bridge is 426 feet long and utilizes two complex intermediate straddle bents to pass over two existing and extremely active railroad tracks.
