GRL Performs Various Q/A Tests on the Harbor River Bridge
Proposed in 2014, the Harbor Bridge replacement project has begun construction with quality assurance testing. The known vacation destination, Harbor Island, is accessed through this drawbridge, located on US-21 in South Carolina. This sea island was originally hunting land that had little need for incoming and outgoing traffic, which was sufficient for the bridge’s original capacity. Read More
New Jersey Hurricane and Storm Damage Reduction Project
Hurricane Sandy hit the coastline of New Jersey at the end of October 2012, causing millions of dollars in damages including 750 homes impacted by the storm in Port Monmouth township, New Jersey. Read More
Bridge Replacement in Growing Cairo, West Virginia
The small town in Cairo, West Virginia began growing in truck traffic when the oil and gas industry started taking roots in the city. Off of a major highway, the original bridge connected route 31 over the North Fork Hughes River. Burgess and Niple reached out to GRL Engineers to bring them on the project for testing. Read More
