Nueces Bay Causeway in 1963Two spans across the bay.

In the opening photograph, traffic heads toward the camera on one bridge while the other roadway runs beside it. That separation was the point of the 1963 project.

Texas Highways called the new span almost a copy of the one built beside it 13 years earlier. Each now carried two lanes of one-way traffic. Together, the bridges supplied a divided four-lane crossing for US 181 between Corpus Christi and Portland. The new crossing, printed page 17

The physical gap between them was only 10 feet, according to the magazine, but drivers in opposing directions now had separate structures. That was a change in how the existing crossing worked. The article’s figure of up to 40,000 cars daily described the system’s intended capacity; the new arrangement was built to handle more traffic as the region grew.

Look farther along the pavement and the bridges appear to run into the same low horizon. From a car, the new arrangement meant a clear direction of travel. From above, it meant two long structures and their approaches occupying a narrow coastal strip. The US 181 historic photographs place this crossing within the longer route into Corpus Christi.

A second bridge was only part of the project. Boats still had to pass beneath the crossing.

The existing navigation channel was relocated. The new elevated crossing and a raised section of the older causeway provided 50 feet of vertical clearance above mean high tide. The magazine says the Nueces County Navigation District financed and dredged the channel relocation, with the Highway Department working alongside the counties and the cities of Portland and Corpus Christi. Channel relocation and bridge work, pages 17–18

In the aerial detail, the hump in the roadway and the narrow strip of land beside it are easy to pick out. Highway work and channel work had to agree on where the opening would be. Drivers needed a continuous road above; vessels needed sufficient space below. The older span could remain useful only after its own elevated section was rebuilt to match the new arrangement.

The article reports long precast concrete beams, some 110 feet long and weighing 50 tons. It also separates the construction expenses: the initial contract, the approaches and the remodeling of the old span. That accounting is a reminder that “a new causeway” can include substantial work on the structure already there. The old crossing was being incorporated into a larger system.

The dedication photograph supplies a detail that belongs to this particular place: three jugs of local water.

On August 12, 1963, officials christened the causeway using water from Nueces Bay, Corpus Christi Bay and the Nueces River. The large sign leaves no doubt about the road or the date. Highway Commission members and local officials stand behind it, with the water being poured at the center. The dedication photograph, printed page 18

The ceremony gathered the governments involved in building and serving the crossing. The magazine identifies Nueces County Judge Noah Kennedy, Corpus Christi Mayor James Barnard, Highway Commission Chairman Herbert C. Petry Jr., commissioners Hal Woodward and J. H. Kultgen, Portland Mayor Pro Tem Jim Fay and San Patricio County Judge Bill Schmidt in the photograph.

The water made an apt ceremonial choice for a road surrounded by it. The magazine’s technical account describes beams, lanes and clearances; this image gives the completed work a local identity. You can also read the distinction between an opening and its coverage directly from the evidence: August 12 is on the sign, while the magazine issue is dated October.
