HDR is responsible for the PS&E of the twin South Main Bridge Approaches of the Houston Ship Channel Bridge Replacement Program for Harris County Toll Road Authority.  This corridor of Sam Houston Tollway East stretches from SH 225 to IH 10 and is broken into 5 segments with multiple design consultants.  HDR’s portion is 5,400 linear feet of bridge, 71 feet wide in each direction.  This twin structure design consists of 42 spans for each the NB and SB bridges.  Foundations consist of large diameter drilled shafts and footings.  Column heights range from 5 feet to 135 feet to achieve 175 feet navigational vertical clearance at the ship channel.  Superstructure is an economical 70 inch pre-stressed concrete TxGirder with up to 153 foot spans.  This challenging project crossed 9 RxR tracks, approximately 90 utilities, a large skewed box culvert, and an operating Kinder Morgan facility.
