National Heavy Civil Division Wins Houston Ship Channel Bridge Project
Posted on September 28, 2017

On Tuesday, September 26th, the Harris County Toll Road Authority (HCTRA) took the first steps toward awarding Ship Channel Constructors (SCC), a joint venture between Traylor Bros., Inc. and Zachry Construction Corporation, a contract for construction of the Sam Houston Tollway Ship Channel Bridge Replacement. The joint venture will build two new landmark cable-stayed bridges across the channel, providing four toll lanes and full shoulders in each direction, while maintaining traffic on the busy water- and roadways along the alignment. Critical to the team’s selection was our extensive cable-stayed bridge building experience, proven ability to work effectively in the water, and resources coming available from both joint venture partners just in time to transition smoothly to this project. Negotiations over final contract language will begin in the next few weeks, after which point we will receive formal award. NTP is scheduled for late this year with project completion in December of 2023.

The contract awarded to the group for the bridge alone was about $568M, below the estimated $612M projected by the Harris County Toll Road Authority. Figure is as of 1/11/18 per HCTRA.

Height is based on 2016 FAA documents

The existing span is notorious locally for it's high incline, narrowness and lack of proper shoulders. Per the linked article, daily traffic had increased 40% between 2013 & 2016, leading to increased congestion. Expansion is also favorable due to increased shipping traffic in the Port of Houston, especially as the Port Commission approves additional infrastructure to serve modern Post-Panamax sized ships.

I just stumbled on this...

...Best. Cable-stayed. Design. Ever.

[The Best Forumer]

This is nice...

[The Best Forumer]

now I wonder when they will do the same for the 610 ship channel bridge.

$1B construction project to replace Houston Ship Channel Bridge starts

Expect some construction work for the next six years or so on the bridge over the Houston Ship Channel.

The Harris County Toll Road Authority has begun a $962 million project to replace the bridge across the ship channel on the Sam Houston Tollway from Texas State Highway 225 to Interstate 10 to handle growing traffic, a spokesperson with HCTRA confirmed and added that notice to proceed was issued on March 19. Currently, the bridge carries about 55,000 cars per day, but that number is expected to grow to almost 158,000 vehicles per day by 2035, according to a Roads & Bridges article about the project co-authored by the HCTRA.

When complete in 2024, Houston Ship Channel Bridge will have two bridges with four lanes of traffic each plus shoulders, per the Roads & Bridges article and Houston Public Media. The current single bridge has only two lanes of traffic in each direction with no shoulder.

There are no plans to close the bridge during construction — the 4-mile-long program corridor will be completed in three phases to maintain all four existing lanes of traffic, per the reports. The first phase includes building a new southbound bridge. When it’s complete in 2021, traffic will then be directed on the new bridge, while construction crews demolish the current bridge and rebuild it to carry northbound traffic.

Isn't there already a bridge in that area that looks almost the same?

This new bridge is an even bigger beast than Fred Hartman is though. A whole lot bigger beast.

[The Best Forumer]

I wonder if it will light up at night.

I think the additional height over the Fred Hartman Bridge comes from the "forks" on the top. Structurally speaking, the roadway and the height should feel about the same.

Ship Channel Bridge nears milestone as work continues on tollway's southbound span

To some drivers, the notion that Harris County was working on a new Sam Houston Tollway bridge across the ship channel might have once seemed like a tall tale.

Now it is a tall pillar of concrete and steel — where workers trudge up and down 15 flights of stairs and counting. It will eventually tower over the ship channel as the priciest piece of road ever for the Harris County Toll Road Authority.

Almost two years from completion, the first phase of the Houston Ship Channel span is becoming more noticeable to drivers on the existing bridge. Even more work will become obvious over the summer, but not without another thing tollway drivers are used to seeing: lane closures.

Still, any sight of a new span is closely watched by commuters and elected officials, including Harris County Precinct 2 Commissioner Adrian Garcia.

“It really is top of mind for some folks,” Garcia said. “Folks are really anxious for a better bridge.”

For construction purposes, the new bridge is actually two bridges, practically inches apart, each carrying one direction of travel. Crews are building the southbound bridge first. When it is complete, all traffic on the existing bridge will move to it, two lanes in each direction, so the old bridge can be demolished and the northbound new span built in its place.

The southbound span — where the new approach lanes have been sitting for more than three years — is scheduled to open by the end of 2025. The demolition of the existing bridge and construction of the second massive span will take until 2028, officials said.

Crews continue work on the new Ship Channel Bridge along the Sam Houston Tollway on Friday, Feb. 2, 2024. Work on the first two of four pillars that will support the new span has risen to the point it is almost even with the existing bridge.

Impressive.

Also thrilled they resisted the temptation to put a lone star somewhere on it.

Given that it's a HCTRA / Harris County project, somehow I'd doubt something like that would be anywhere in the design. Can't think of any of the roads that they manage having a design element like that.

Other surrounding agencies or the state... that's a different story.
