“Think traffic on Mopac is bad now, image 70,000 more cars per day once SH45 SW is built”

Is this what Austin needs? We don't think so.


CTRMA and TxDOT continue to rush ahead to convert Mopac from a local commuter highway to a second, partially tolled Interstate 35 through Austin, in their less-than-honest, piecemeal way. At the same time, resistance to this piecemeal scheme continues to grow.

Public comments needed on “Mopac Intersections” draft environmental assessment: The CTRMA/TxDOT partnership is currently soliciting public comments on a draft environmental assessment (EA) on their “Mopac Intersections” piece of the proposed 45SW/Mopac expansion toll loop. This would be a two mile long addition of six lanes, three in each direction, in the central, currently green and beautiful median, from the southern end of Mopac to north of Slaughter Lane. This segment also includes overpass bridges crossing Mopac at Slaughter Lane and LaCrosse, converting the existing Mopac lanes into frontage roads in this two mile stretch.

This “Mopac Intersections” segment would connect the proposed SH 45 SW toll road to the south to the large “Mopac South” project to the north. It’s the “Mopac South” project that would include the double-decker bridge over Zilker Park and Lady Bird Lake and connect to the “Mopac Improvement Project” toll lanes currently under construction from Cesar Chavez north to Parmer Lane.

Please take a few minutes to go HERE and send written comments on the draft “Mopac Intersections” environmental study by August 10. Attend a public hearing this Thursday, July 30, at Bowie High School Read More...



On Monday May 11th, our transportation deciders, the "CAMPO" board, voted 19-0-1 to approve a $35 billion "Long Range Plan" for the Austin five county region. Thanks go to Travis County Judge Sarah Eckhardt for at least abstaining and refusing to support this wasteful road map to failure. CAMPO and TxDOT's own experts admit that the plan will lead to worse congestion in the future, despite billions in new construction, much of it slated for building toll roads and adding toll lanes to existing highways.

Thanks also go to Austin Council member Ann Kitchen for putting language into the so-called "2040 plan" directing that ongoing Mopac studies evaluate options that would improve traffic flow without building four (4) toll lanes and a double-decker bridge over Lady Bird Lake.

Despite over 2000 letters, emails, and petition signatures, the 2040 plan also includes the proposed conversion of Mopac into Interstate 35 by way of building the SH 45 SW toll road. We don't know why City of Austin and Travis County representatives who campaigned against SH 45 SW and the expanded Mopac toll loop voted for the final 2040 plan.Read More...
