Project Location
– East of US 75 to South of the I- 635/I-30 interchange Project Length: 11 miles Approximately a 2-mile section of reconstruction on I-30 for transition
TxDOT I-635 East Project SPRING 2020
Congestion Relief – Increased General Purpose Lanes Capacity Increase area mobility and local connectivity – Construction of continuous frontage roads in each direction
– “Grandfathered” existing managed lane
Improve Safety – Address existing design deficiencies
Purpose and Need
TxDOT I-635 East Project SPRING 2020
Full reconstruction of the existing 8 general purpose lanes to 10 general purpose lanes, with auxiliary lanes at entrance and exit ramps Full reconstruction of the existing 1 concurrent tolled managed lane Full reconstruction of the discontinuous frontage roads to continuous frontage roads up to Town East Boulevard. Full reconstruction of city street overcrossing and undercrossing structures Full reconstruction of the I-30/I-635 Interchange

KCS Railroad Underpass
TxDOT I-635 East Project SPRING 2020
Elimination of 2 railroad underpass structures at EB & WB I-635 frontage roads just east of Garland Ave. & KCS Railroad track. Frontage roads will be same elevation as proposed mainlanes in this area. Loop ramps added to the north and south of I-635, replacing at-grade signalized intersections in the approved schematic. Loop ramps to provide connection from EB frontage road to Garland Ave. West-to-East traffic movement no longer via a U-Turn lane, but instead maintained through the proposed loop ramp. New East-to-West U- Turn moved approx. 1000 ft. to the west
At-grade signalized intersection at the WB frontage road to replace jug handle connection from Shiloh Rd. Garland Ave. & Shiloh Rd. maintained at same existing elevation, instead of depressed roadway design. Entrance ramp from Garland Ave. to EB I-635 mainlanes shifted approx. 1000 ft. to the east. EB I-635 exit ramp to Northwest Hwy. shifted approx. 300 ft. to the west.
