SH 360 Study

The SH 360 improvement project is designed to expand SH 360 through Arlington and Grand Prairie from I-20 to just north of I-30, including the I-30/SH 360 interchange. Most of the proposed improvements are not currently funded.

The existing SH 360 Corridor includes three general purpose lanes each direction. Proposed improvements include four lanes each direction from I-30 to Abram Street, with allowance for possible future expansion to five lanes each direction built into the median. Four lanes each direction would be constructed from Abram Street to I-20 within the existing 12-foot-wide inside shoulders. Division Street and the adjacent Union Pacific Railroad bridge will be reconstructed to accommodate the new SH 360 main lanes and permit continuous frontage roads in approximately 2007. Flyover ramps directly connecting the main lanes of I-30 to SH 360 are also planned.

The SH 360 improvements have an estimated cost of approximately $380 million, including the directing-connecting ramps at the I-30 interchange, right of way acquisition, contingencies, and design-related costs. This cost does not include approximately $95 million in improvements for I-30 between Ballpark Way and the Dallas County line.

The purposes of the SH-360 corridor improvements are to relieve north-south traffic congestion; improve mobility, safety and air quality; and maintain accessibility to businesses and public facilities.

TxDOT received a Finding of No Significant Impact in February 2007.
