Jarvis Bridge

Map 

Description 

This bridge replaced a two-span Pratt truss bridge, the largest span being a through truss with A-frame portal bracing stretched horizontally and measured at approximately 120 feet. The shorter span was a pony truss bridge. Both were pin connected. The bridge was replaced after inspection revealed that many connections were weakening and the roadway was in horrible shape. The bridge was closed to traffic in 1972 and was replaced the following year.
