TxDOT's solicitation for consultants this month is as large as I ever recall seeing in terms of dollar value

The big contracts are around $368 million, with the smaller contracts (like construction inspection) pushing it to around $400 million. However, solicitations have been slow for the last few months, so there could be some accumulation.
What's interesting is that there is a lot of work for route studies, environmental studies, right-of-way mapping and public involvement. Work is mainly in the DFW, Austin, San Antonio and Houston districts.
However, details are cryptic in these solicitations, so I can't correlate them to any specific projects. I'm thinking that in Houston this could be for the Grand Parkway sections B and C, and possibly right-of-way for I-69 (although I think there is little of ROW work remaining in Houston). In Dallas it could be for Loop 9 south or the Collin County outer loop.
This seems to be a lot of work. Contracts for route studies are what you expect to see for big new corridor studies. So I'm thinking there could be something big and new about to be launched, particularly in Austin - maybe SH 45 west extension (?)
