Besides widening in Bell and McLennan counties are there plans to widen the freeway the whole way from Dallas to San Antonio?
I have not looked at the I-35 Corridor Advisory Committee Plan (August, 2011), but it may give you an answer. You also might enjoy just going through it in general. In addition, I think serious consideration is being given (similar to Texarkana I-69 corridor) to possible leasing of air rights for the Freight Shuttle to help pay for some of the I-35 improvements.
I just had the opportunity to sit down and read the I-35 Corridor Plan and it was quite a lot of info. Thanks again Grzrd!
You're welcome dariusb! I just took a brief look at it myself and found the following
right-of-way recommendation to be interesting (page 26 of document; page 30/122 of pdf):
Consider common rights of way for rail and highway/multi-modal alignments, where feasible.
That recommendation fits in well with the recent
TxDOT RFP regarding modes of freight transportation like the Freight Shuttle. Also, in regard to your initial question about Dallas to San Antonio plans,
page 11/21 of this pdf indicates that the Dallas to San Antonio section of I-35 might be the first segment of a Freight Shuttle along the I-35 corridor and down to Mexico.
EDIT
I recently made the following post in the
"TxDOT RFP For Leased ROW Freight Transportation" thread and decided to add it here, as well:
TxDOT received a proposal for the I-35 corridor, I assume for Dallas to San Antonio, which is currently under review. Here's part of an email reply I received from Roger Beall at TxDOT:
Thank you for your inquiry. We received one proposal on October 3, 2011 and their proposal was for leasing the right-of-way within a portion of the IH-35 corridor. The Texas Transportation Commission has not acted on moving forward with lease negotiations. We are in the process of clarifying some items from the proposer. No time frame has been set for Commission action to approve or disapprove moving forward with lease negotiations.
Please let me know if you have any other questions.
