TxDOT and Arup-CFC resolved one of the five design issues, deciding to add additional steel reinforcement to the delta box girders, and work resumed on those sections as of November 3, 2022. Construction of the approach spans has continued despite the halt on the main span and towers, and were over 80% complete as of October 28, 2022.

The new Harbor Bridge will be a cable-stayed suspension bridge with a 1661-foot span, rising to a height of 538 feet at the peak of each support pylon. The bridge will allow passage of ships up to 205 feet above-waterline height. The concrete construction technique used for bridge segments have a 170-year estimated life.
TxDOT gave Flatiron/Dragados 15 days to address its public safety concerns with the new Harbor Bridge design or be removed from the embattled project.
Construction on the bridge was on the planning boards by the Texas Department of Transportation (TxDoT)as far back as 1962. Originally planned with a 400-foot (120 m) mainspan, it was rejected by the Army Corps of Engineers for fear that the narrow main span was a hazard to ships on the Ship Channel.
In 2010, TxDOT was reorganized into four regions, North, South, East, and West. The regions are designated as Regional Support Centers. The number of districts remained the same. Each district, managed by a district engineer, is responsible for the design, location, construction, and maintenance of its area transportation systems.
AASHTO LRFD Bridge Design Specifications. This manual is the base bridge design manual that all DOTs use across the US. Manual for Assessing Safety Hardware (MASH), crash testing criteria for safety hardware devices for use on highways; it updates and replaces NCHRP Report 350.
Efforts to construct a bridge over the Houston Ship Channel were stymied until the Texas Turnpike Authority (TTA) was able to do so as a toll facility in the late 1970s. As a result, the section of Beltway 8 from I-10 to SH 225 on the east side of Houston was removed from the state highway system on July 24, 1978. [ 8 ]
