In 1925, the 39th Legislature enacted laws providing the basis for TxDOT’s low-bid process. As a result of this legislation, the department established its low-bid construction and maintenance contract letting process, which includes providing a public notice of the intent to offer work, issuing proposals, receiving proposals, opening bids and awarding contracts. Here you will find information related to that process.

Statewide Letting

Letting is the official receipt and opening of bids and determination of the apparent low bidder. TxDOT conducts its statewide low-bid construction and maintenance contract letting in Austin on two consecutive days each month. The letting schedule is available for the current and following fiscal year.


Note that to advance the public health goal of limiting face-to-face meetings (also called “social distancing”) to slow the spread of COVID-19, the April 2020 statewide letting will only be open to bidders via live video stream. In-person attendees will be turned away.

Special accommodations: All monthly lettings are conducted in English. If you have a special communication accommodation or need for an interpreter, a request can be made. If you have a disability and need assistance, special arrangements can also be made to accommodate most needs. Please contact (512) 416-2500 at least one week prior to the scheduled letting, as some accommodations may require additional time to arrange.

Local Lettings

Projects estimated at less than $300,000 are let at the headquarters for the district in which the improvement is to be made, as advertised in the proposal.

To limit potential exposure to the Coronavirus and in conjunction with the Governor’s March 16, 2020 press release, TxDOT may also host local lettings virtually (via WebEx or phone conference). If a local letting is hosted virtually, a note will be posted on TxDOT's FTP site for the specific project along with the link and call-in information. Use this information to listen to or view the reading and openings of the bids. If you have any questions, email the point(s) of contact listed in the project proposal.
