It is 836 feet long and was originally called the Royal Street Bridge.","why_significant":"The bridge is argued to be an excellent and one of a small number of intact open spandrel concrete arch bridges in Texas, significant for engineering under Criterion C at the state level. It is also significant under Criterion A at the local level for its role in Fort Worth and Tarrant County transportation as a link on the Jacksboro Highway.","narrative":"Henderson Street Bridge carries four lanes of traffic over the Clear Fork of the Trinity River on the western edge of downtown Fort Worth. Built in 1930 and first called the Royal Street Bridge, it measures 836 feet and combines a 124-foot open spandrel concrete arch with 14 concrete girder approach spans. City engineer C. Milo Thelin and consultant Ira G. Hedrick of Hot Springs, Arkansas, designed it, and Frank Parrott of Dallas built it. Arcaded concrete handrails, cantilevered sidewalk brackets and curved girder fascias give it a distinctive appearance. It was part of a city plan to make Henderson Street a major north-south arterial and to link downtown with the Jacksboro Highway toward Lake Worth and beyond. It was listed for engineering significance as one of few intact open spandrel arch bridges in Texas, and for its importance to local transportation. Alterations include removal of original light standards, though integrity is described as high.","period_of_significance":"1930-1961","architect_builder":"Hedrick, Ira G., Consulting Engineer; Thelin, C.
