Norfolk Southern Rail Road Over the Grand River
The Norfolk Southern Railroad Bridge over the Grand River in Painesville, OH, was built in 1905 and reinforced in the 1940’s. High maintenance costs and a restrictively large footprint in the Grand River led to the decision to replace the bridge. The Great Lakes Construction Company was awarded the contract and chose Suburban Maintenance Construction, Inc. to install 26 drilled shaft foundations ranging from 4’ to 7’ diameter and up to 93.5 feet in length. GRL Engineers, Inc. provided the SQUID equipment, data evaluation and reporting. Read More
