Cotton Belt/Silver Line Update (this is really long)
DART has postponed their bi-annual meeting with the community to February 9th, from 6:30-8:30 pm. The meeting will be held at the Texas A&M AgrilLife building, 17360 Coit Road.
Preston Green Park pedestrian bridge update - concrete pouring and construction continues. A new consultant for the park makeover is being hired.
Meandering Way upate - only one lane each direction remains open for vehicles. Construction continues.
Dickerson update - concrete pouring continues. This section is nearing completion.
Coit update - right lane closures to prepare for traffic signals at Alacasia, Sugar Cane and Osage continue.
Hillcrest update - vehicle traffic remains one lane each way - NEW: the permit for DART to begin drilling has been issued effective 1/23/23 for 12 weeks. After the 12 weeks, they will have a permit for another part of the project at Hillcrest. Here are details for the next 12 weeks:
Bridge Abutments, Pump Station, and Approach Slab Construction Narrative:
ATS will begin by installing the 60in drill shafts for Abutment #1 (west side of Hillcrest) and the adjacent 60in zone of influence retaining wall shafts from North to South followed by the 36in approach slab drill shafts. Drill shafts will remain buried after completion. Once the drill shafts are complete, ATS will move their rig to the east side to begin drilling of Abutment 2 (east side of Hillcrest), zone of influence shafts, and pump station drill shafts. AWH structure crews will begin construction of Abutment #2 & approach slab, upon completion of drilling activities. Urban Infraconstruction will then place the pedestrian bridge Abutment #2. All work will happen in linear fashion not concurrently due to spatial constraints.
Pedestrians will be shifted over to the southbound right lane closure and protected on each side by barrier and Crowdcades. This path will be ADA compliant.
Contractors Involved:
• Buyers Barricades – Setting of traffic control
• ATS Drilling – Install drill shafts
• AWH – Daily traffic control maintenance, construct track bridge abutment and approach slabs
• Urban Infraconstruction – Construct pedestrian bridge abutments
Start Date: 1/23/23
Duration: 12 weeks
Campbell update - NEW: the permit for DART to begin work at has been issued effective 1/30/23 through 7/6/23. Two lanes of traffic will remain open in each direction.
Limits of the pavement reconstruction will extend 160’ west of the proposed double track crossing and will include the reconstruction of the driveways at Bent Creek North Condominiums and Prestonwood Trail Apartments. East of the double track crossing, the limits of the pavement reconstruction extend approximately 275’. Pedestrian access with adequate lighting, drainage, and other safety provisions through one side of the construction zone will be maintained throughout the road closure. The proposed drainage at the Campbell Rd crossing includes removing 2 existing RCP culverts on either side of the track crossing and 3 inlets. The new design will replace these with an 18” class iv RCP culvert and 2 curb inlets 70’ east of rail crossing. Additionally, 2EA – type Y inlets will be replaced in the rail guideway north of the road that will tie into the existing 39” storm drain running under Campbell Rd. Wet utility modifications include relocating the existing 16” water main on the north side of Campbell and encasing it with “Class B+” embedment per the DWU drawing, which will protect these wet utilities under the 2 proposed Silver Line tracks. The proposed Campbell Road double track crossing will require franchise utility relocations by Explorer, Sprint & Qwest. The existing Sprint FOC west of the tracks and the existing Qwest FOC east of the tracks will require a relocation. Both existing FOC will be abandoned and will be relocated in a joint duct along the eastern side of DART’s ROW. The Explorer high pressure gas line will be relocated from the western side of the tracks to the eastern most side of DART’s ROW. All franchise utility relocations have been completed.
AWH proposes to construct the Campbell Road crossing under a multiple phased partial closure to allow for 2 lanes of traffic to be open in each direction at all times.
Pedestrian access around one side of the work area, and access to the residences on the southeast and northeast quadrants of the crossing will stay open throughout the entire duration of Campbell Rd crossing construction, which is noted in the TCP plans. Additionally, this construction will not be done concurrently with the proposed crossing work at Davenport East or Davenport West.
CROSSING CONSTRUCTION NARRATIVE: AWH proposes to construct the Campbell Road crossing under a 7-phase closure. AWH will follow the Dallas’ ILA work hours on weekdays from 7AM – 9PM and on weekends from 9AM – 7PM.

Saw cut full width of pavement for proposed RCP alignment 3. Temporary lane closures set up for pavement removal, excavation, pipe install, and backfill. 4. Steel plate at end of day over excavated sections. 5. Repeat as pipe is installed across the roadway. 6. Install temporary asphalt.
PHASE 1: In Phase 1, the traveling public will be pushed to the 2 outside lanes in either direction. The inside lanes next to the median will be closed to construct the new profile of Campbell Road.
