Description:

TxDOT proposes the reconstruction of the I-345 facility for 2.848 miles. The proposed improvements would consist of depressing six 12-ft mainlanes (three in each direction). Various configurations of 12-ft auxiliary lanes (up to four) would be included with 10-ft shoulders. Discontinuous frontage roads (one typical 12-ft lane southbound and three typical 12-ft northbound) would be constructed along the facility between Bryan St. and Hall St. The project would include 6-ft sidewalks or 10-ft shared-use paths (SUPs) at cross streets (both sides). A 10-ft SUP would be included at a minimum on one side of the frontage roads within project limits. All improvements would occur within existing ROW which varies in width from approx. 280 to 635 ft. Cross/side streets would be realigned and reconstructed to accommodate the complete reconstruction of I-345 and its interchanges with SS 366 and I-30. The project would include rebuilding the interchange at I-30/I-345 (including eight direct connectors), connections to SS 366 (Woodall Rodgers), and a Dallas Area Rapid Transit (DART) wye connection. Crossings involved in the reconstruction include Hickory St., Dawson St., Louise Ave., I-30, S. Good Latimer Expy., Canton St., Commerce St., Main St., Elm St., Pacific Ave., Live Oak St., N. Good Latimer Expy., Ross Ave., and SS 366. 

Proposed drainage would be gravity drain, meaning no pump station would be required. The proposed project requires 0.85 acres of drainage easement for a 48-inch reinforced concrete pipe (RCP) and junction structures at approximately 60 feet deep. The pipe would convey storm water from the proposed I-345 facility main trunk line to the existing Town Branch storm drainage system. Two options are under evaluation. Option 1 would consist of a 0.30-acre easement within Carpenter Park and Pearl St. This option would allow for an RCP connection to the existing system. Option 2 would consist of a 0.85-acre easement along Pacific Ave. This option would be needed for an RCP connection along Pacific Ave. to the existing system. No additional new right of way is required.
