It was built in 1938 by the City of Houston.","why_significant":"The nomination argues significance under Criterion C in engineering at the state level. It is one of 70 multi-span variable depth plate girder steel bridges in Texas and is notable for the length of its main span. It is also a typical example of late City-Beautiful design in Houston, with Art Deco details such as battered pilasters on the piers and Deco motifs on the railing posts and wingwalls.","narrative":"Carrying South Jensen Drive over Buffalo Bayou in Houston, this 500-foot bridge was completed in 1938 to replace an earlier 1920s steel drawbridge. City bridge engineer J.G. McKenzie designed it, and Russ Mitchell, Inc. built it. Three continuous steel plate girder spans rest on concrete piers and bents, with concrete approach spans at both ends. The main span measures 143 feet, with 62 feet of vertical clearance, chosen so ships using the Houston Ship Channel could pass beneath. The roadway is 40 feet wide and carries four lanes. Art Deco touches include battered pilasters on the piers, half-round end posts on the approach walls, and steel picket railings with vertical lines on the newel posts. The crossing linked the warehouse district north of the bayou with the commercial center to the south. It is one of 70 multi-span variable depth plate girder bridges in Texas, notable for its long main span and its late City-Beautiful styling. It retains its original design, materials and setting.","period_of_significance":"1938","architect_builder":"Bridge designer: J.G.
