As we step into 2026, Texas doesn't hit the brakes on its infrastructure projects, with December being a particularly bright spot in terms of progress. Over in Austin, the Texas Department of Transportation (TxDOT) has geared up for the I-35 Capital Express Central project, a crucial overhaul not seen since `'74. According to a TxDOT report, the MLK bridge reconstruction is in the mix, along with developing the Lady Bird Lake segment and constructing vital drainage systems to facilitate the main lane lowering from Holly Street to Airport Boulevard.

The ambitions of Austin's project stretch to include a network of 22-foot-diameter tunnels and related infrastructure, set to address stormwater like a pro before the excavation gets rolling. The two tunnel boring machines, specially ordered from Germany, will join the fray this year, signaling a move towards greater mobility, safety, and flood resilience in the city.

Let's cruise to North Texas and the Panhandle, where Amarillo District's TxDOT team is pushing on with not one, not two, but five major safety and capacity efforts. These include an expansion of I-27, turning lanes and intersection enhancements on State Loop 335, and a series of upgraded lighting and drainage on FM 1061 and FM 2590, not to mention the shared-use paths and median barriers on Business I-40. This package, costing hundreds of millions, is setting the stage for safer roads and fewer accidents.

In San Angelo, locals driving along US 67 finally got a break as the expressway reemerged from its flood-induced hiatus. The former metal pipe culverts, relics from the '80s, have given way to sturdier concrete solutions. Meanwhile, in San Antonio, the U.S. 90 Expansion Project has officially left the starting blocks. With a tag price of $473 million, it plans to transform the highway from a four to a six-lane wonder, peppered with continuous frontage roads, a shiny flyover ramp to Loop 1604, and all-new turnaround bridges.

Swinging back to Bexar County, FM 1518 is stretching its legs with wider lanes, a raised median, and pedestrian pathways. Parts of this project, marked at just under $73 million, were rounded off in December, lighting the way through 2028. As these and other projects continue unspooling into the new year, TxDOT's commitment to enhancing Texas' roadways remains steadfast and unfaltering.
