The biggest contributor to the congestion that is common in the subject interchange is the “weaving” of traffic. There are also capacity issues related to the population and traffic growth in the south Arlington and Mansfield areas. Examples of the weaving problem are the northbound US 287 traffic to westbound IH 20 weaving with the westbound IH 20 traffic to northbound IH 820/US 287, and the southbound IH 820/US 287 traffic to southbound US 287 weaving with the lane changing eastbound IH 20 traffic.
The Texas Department of Transportation (TxDOT) is proposing to reconstruct the 1-20, 1-820 and US 287 interchanges in southeast Tarrant County. The limits of proposed improvements include 1-20 from Forest Hill Drive to Park Springs Boulevard, 1-820 from 1-20 to Brentwood Stair Road and US 287 from Bishop Street to Sublett Road. Total length is approximately 16 miles. The proposed project is also referred to as the “Southeast Connector.” The purpose of the meeting is to present the recommended improvements and to receive public comments on the proposed project. The Public Meeting will be an open house format, with no formal presentation.
The Texas Department of Transportation (TxDOT) and the Federal Highway Administration (FHWA) have completed a Major Investment study for IH 820 and IH 20 in southeast Tarrant County, Texas.
The purpose and need for this project was determined early in the process and stemmed from three major factors: 1) anticipated local and regional population and employment growth within the IH 820 corridor and the Dallas/Fort Worth Metroplex; 2) the demand for additional transportation capacity within the IH 820 corridor as a result of increased population and employment; and 3) design deficiencies throughout the existing corridor facilities that contribute to congestion and a high frequency of traffic accidents.
This 2005 Report documents proposed changes in access to the IH 820 and IH 20 facilities. It also provides the background information for the FHWA determination to ensure that the proposed project will not have a significant impact on Interstate highway safety or mobility. This report follows the policy guidance set forth in the Federal Register on February 11, 1998, under the title “Notice of Policy Statement.”
Problem areas and Issue Overview:
In general, the 287/I-20/820 interchanges are poorly designed and are unable to handle current traffic levels, much less projected future traffic. The number of lane changes that drivers must endure to move north, south, east, and west through this portion of Tarrant County lead to overall congestion and generally unsafe conditions. The left exit for Business 287 further complicates and interrupts traffic patterns. Entrance and exist ramps are, in general, poorly designed and create severe congestion and unsafe conditions.
