TxDOT

Motorists on I-20 in Midland County will see another traffic change when a project to tear down the existing bridge and replace it with a new one at Cotton Flat Road begins the week of Sept. 26.

• A $25 million federal BUILD grant is paying for part of the $68.5 million project. The BUILD grant came with scheduling mandates which is why TxDOT will have three consecutive overpass projects going simultaneously along the I-20 corridor in Midland County.

• The first phase of work will consist of service road improvements on either side of Cotton Flat. The work will stretch to SH 349 to the east and dovetail with the Midkiff project to the west. The service roads will be down to one lane in each direction. The north service road will be one way westbound; the south service road will be one way eastbound.

• In the first phase, a concrete barrier will separate traffic on the service road from workers widening the road to the inside. The Cotton Flat bridge will remain open in this first phase.

• Once the frontage roads are widened to three lanes in each direction, the main lane traffic will be moved to the service road for construction of the new overpass that will carry I-20 main lanes over an improved Cotton Flat Road bridge similar to the Midkiff Road bridge to the west.

• The existing Cotton Flat Road configuration requires a different construction approach than the Midkiff and CR 1250 projects. The existing Cotton Flat bridge will be removed early in the project timeline. The existing bridge support structure needs to be removed to accommodate three lanes on the service roads.
