Construction is expected to begin in September on a $4 billion, 2.5-mile-long highway through the heart of downtown Dallas.
Construction on the highway will cut through the old Dallas Public Schools campus.
Construction is expected at the end of 2021.
It is estimated that the project will take about 20 years to complete.
Construction will be held to a start date that is still being determined, according to the city.
The project will be funded through $4.5 billion in bonds.
The bond funds the construction of the bridge, which will run from Interstate 35E to I-35W, along with the construction and rehabilitation of roads.
Dallas officials said the highway is the largest and most expensive highway project in the state’s history.
The city expects to build more than two million square feet of highway over its next 25 years.
The Dallas City Council will consider the bond proposal Tuesday, but it’s not expected to be approved until late in the legislative session that begins in January.
