LJA is providing Construction Engineering & Inspection services for the $570M reconstruction of the existing segmental 4-lane bridge over the Houston Ship Channel with an 8-lane cable-stay bridge design that provides a larger opening for the operation of vessels.
The new Houston Ship Channel Bridge cable-stayed main span structure features a free span of 1,320’ over the Houston Ship Channel and is the centerpiece of the overall program to widen the Sam Houston Tollway (East). The new bridge provides eight lanes for vehicular traffic and more than 187’ of vertical clearance for navigation, allowing future widening and deepening of the channel by the Port of Houston. The 514’ tall sculpted towers will result in a dynamic experience for drivers as they pass under the varying angles of each stay cable.
LJA has been tasked with providing a full-time resident engineer – in addition to a full-time inspection crew – responsible for inspector assignments, plan reviews, cost control, and RFI responses; and construction inspection including daily monitoring, documenting, payment support, and issue escalation on multiple segments of the project including the north and south approaches and main-span towers. Recent work includes foundation for the North Tower (40 – 96” x 246’+ drilled shafts with mass placement footing), North Approach substructure and bridge deck, ancillary items necessary for construction including 1+ mile of fiber optic cable, and construction of the precast yard and buildings to be used to cast the segments of the main span.
