Congestion Management Strategies

Congestion Management Strategies (CMS) for the SH 360 corridor include instituting an Employer Trip Reduction Program (ETR) and improved park-and-ride facilities. The ETR is a public/private initiative that targets large employers in the study area to provide flex-time, telecommuting and/or ride matching (to encourage ride sharing). Park-and ride facilities are suggested near SH 360 and Mayfield, and SH 360 and Abrams. These locations are subject to review and modification. CMS has estimated capital costs of $2.2 million and annual operating costs of $0.55 million. CMS strategies are estimated to meet approximately 2% of the SH 360 corridor improvement goal.

Bicycle/Pedestrian Improvements

Bicycle and pedestrian facilities offer mobility benefits by providing alternatives to motorized travel, especially on short trips. A combination of on-street bike routes, bike accessible streets, sidewalks, trails, and support facilities such as bike parking and maps, are recommended with an estimated cost of $21.7 million. These bicycle and pedestrian improvements are estimated to meet approximately 2% of the SH 360 corridor improvement goal.

Rail Transit Improvements

Rail transit service using the Dorothy Spur was investigated. The Dorothy Spur is an existing freight line used by the UPRR that extends from the Trinity Railway Express line near Centreport, down to the east-west UPRR tracks paralleling Division Street in Arlington. (Note that at the north end of this segment, the bridge crossing the West Fork of the Trinity River is actually washed out.) Several concerns were identified in using the existing rail line, including active freight use on a single track, numerous spur tracks, and narrow right-of-way. The median of Great Southwest Parkway is suggested as an alternate route for investigation in future rail studies (by others). Commuter rail is considered part of the baseline improvements to the SH 360 corridor, and is estimated to carry about 800 person trips per day, or about 1% of the SH 360 corridor improvement goal.

Arterial Improvements

Upgrades to three major arterials parallel to SH 360 were evaluated for their potential impact to north-south travel in the SH 360 corridor. Most of Collins St. from IH 20 to SH 183 is already programmed for expansion to six lanes, with portions currently under construction. New York Ave./Ballpark Way was studied as a continuous six-lane arterial, but due to right-of-way constraints, local opposition, and limited traffic improvements, this alternative was dropped from further consideration. Great Southwest Parkway is recommended for improvement to a continuous six-lane arterial, consistent with Thoroughfare Plans for Arlington and Grand Prairie, at an estimated cost of $78 million. The arterial improvements are estimated to meet approximately 9% of the SH 360 corridor improvement goal.

SH 360 Improvements

The main lanes of SH 360 from Abram Street to IH 30 will be totally reconstructed as an 8 lane freeway, with allowance for possible future expansion to 10 lanes built into the median. Flyover ramps directly connecting the main lanes of IH 30 to SH 360 will be added. 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. The existing inside shoulders of SH 360 south from Abrams Road to IH 20 are constructed 12 feet wide, with full depth pavement to facilitate expansion to eight lanes. All widening in this segment will be to the inside of the existing lanes. The SH 360 improvements have an estimated cost of approximately $380 million, including the directing-connecting ramps at the IH 30 interchange, right-of-way acquisition, contingencies, and design-related costs. This cost does not include approximately $95 million in improvements for IH 30 between Ballpark Way and the Dallas County line. The SH 360 improvements are estimated to meet approximately 36% of the SH 360 corridor improvement goal.
