Even before construction was complete on the Merchants Bridge, the older of the two bridges, TRRA began work on the MacArthur Bridge, an ongoing project that has already resulted in the replacement of a single span truss with a three-span girder bridge, demolition of the abandoned roadway bridges and installation of a retaining wall.
The $222-million replacement of the Merchants Bridge, which serves five Class 1 railroads and Amtrak, was completed in 2022. The original bridge dated to 1890 and was designed by George Morrison, who designed some of the first large-scale steel truss bridges in the country.
