The bridge features six open-spandrel concrete arches spanning 659 feet (201 m) and carries tens of thousands of vehicles daily across the lake.

At that time, the bridge was left without street lights, perhaps because of material shortages relating to World War II; these were later added in 1955.

[4] On July 7, 1994, the bridge was added to the National Register of Historic Places in recognition of its architectural significance and its continuing importance to Austin's transportation infrastructure.

[3] Today, the bridge still carries Lamar Boulevard (now designated part of Texas State Highway Loop 343) across the Colorado and supports substantial pedestrian and vehicular traffic daily; a 2011 study by the Downtown Austin Alliance asserted that the bridge now experiences more than twice the traffic volume it was designed for.

The piers (originally visible, but now largely submerged) and pedestrian guardrails show Art Deco details, such as vertical fluting, which indicate the period of the bridge's construction.

A series of slender vertical columns rises through the open spandrels to support smaller longitudinal arches and transverse floor beams immediately beneath the deck.
