North Texas highway closures to watch during MLK weekend

• The projects are projected to cost over $9.6 billion. Another $9 billion in construction is scheduled to begin over the next four years.

The latest: In downtown Dallas, all lanes of Interstate 30 will be closed from 10pm Friday to 5am Monday. The closure, part of a project to widen the highway, will span between the Interstate 35E and Interstate 45 interchanges.

• TxDOT expects the closure will cause significant delays, with cars being routed to Highway 366.
• Parts of Cesar Chavez Boulevard, Cadiz Street and Akard Street are also closed for construction.

Zoom in: In Tarrant County, all of the free westbound lanes of Interstate 820 from Rufe Snow Drive to Interstate 35W will close from Friday night to Sunday morning. Drivers will be able to use the 820 toll lanes at no cost.

• Parts of State Highway 121 and State Highway 183 will also be closed over the weekend.

In Dallas County, there will be construction in the Harry Hines area Monday on I-35E near the I-635 interchange. TxDOT says the daytime road work will not impact the main lanes.

The intrigue: It feels like I-35 has been under construction our entire lives.

• Some of the interstate's northbound lanes in Denton will be closed through Wednesday, along with the exit ramp to I-35W.

What they're saying: Slow down, look for detour signs and build in extra travel time, TxDOT says.
