Providence River Bridge - The Iway Bridge • First network arch built in the United States • Saved 33% in structural steel costs over vertical cable options • First skewed network arch bridge and first with 3 arches • Built offsite and ‘floated’ over 12 miles up river into place, as featured on The History Channel’s MEGA MOVERS show • Float was finalist for an AASHTO America’s Transportation Award for Innovative Management given to the Rhode Island Department of Transportation (RIDOT) • First major use of self-propelled modular transporters (SPMTs) in Rhode Island Network Arch Bridges A network arch bridge is an arch bridge with inclined cables that cross more than once. Because moments are greatly reduced, arch and tie cross sections are very light. Advantages • Ideal for 300’–1,500’ span range • Cost-effective: 30-60% possible cost savings • Inclined cables have smaller deflection than vertical cables option • Faster completion possible: lighter weight allows moving for concurrent bridge/foundation construction and float Owner: Rhode Island Dept. of Transportation All Photography: Frank Giuliani
