Loop 1 (Mopac Blvd) 2001 Preliminary Schematic, for Historical Reference

Last updated 14-December-2003

The official project web site: http://www.mopac183.com/

This is the design that stirred up the protest army at the 9-April-2001 public hearing at the Austin regional planning council meeting. The opposition was about 800 people strong and even had former Texas governor Ann Richards on their side. The study for improvements to Loop 1 was suspended in February 2002 and remains suspended as of this writing in December 2003. Austin now has a regional mobility authority, and if anything happens in the future for this project it will likely be through the mobility authority.

These schematics represent the leading design candidate as of 2001. If and when the Loop 1 study is resurrected, the plan could be similar to this design, or it could be different.

This design was an option under consideration in 2001.
As of December 2003, planning for future improvements to Loop 1 is on hold.

Downtown interchange (High res. 267K)
Downtown interchange (Med res. 134K)

The Westover interchange would be permanently closed.
Westover to 35th (High res. 253K) Most right-of-way acquisition is on the west (top) side.

35th-Camp Mabry (Med res. 162K)
The design shows a major re-configuration of this interchange, including removal of the cloverleafs and a new entrance ramp to northbound Mopac that would require the demolition of a TxDOT building.
Camp Mabry (High res. 260K)
Camp Mabry (Med res. 130K)
The design shows that many Camp Mabry buildings would be affected, and the jogging trail would need to be re-routed.
