[2]: 10 This first trestle was gradually worn out by heavy railroad traffic and periodic flooding in Shoal Creek, and in September 1908 the Austin City Council urged the I–GN to replace the increasingly dangerous structure with a more durable crossing.

[3] By October the trestle had been replaced with a wooden beam bridge,[4] but this structure soon needed to be upgraded to accommodate the heavier locomotives that came into use in succeeding decades.

[6] By the 2010s nonprofits had advanced multiple proposals to convert the trestle to a rail trail as part of an urban linear park, similar to New York's High Line.

[7] In 2021 the Shoal Creek Conservancy proposed that the trestle be nominated to the National Register of Historic Places, in part to access federal tax credits for the rehabilitation of listed sites.

It has eleven roughly equal spans between twelve bents made of six to eight piles each, with diagonal braces joining the timbers.

Some elements of the trestle were replaced with material similar to the original construction to improve its structural stability and safety at some point in the 1990s or early 2000s.
