SR 135 Widening from US 441 East to SR 32, including CSX Railroad Separation, Coffee County, Georgia

2.9 mile widening and new location of existing rural 2-lane to a 4-lane divided urban highway with 20-foot raised median and 4-lane rural highway  with 14’ flush median on SR 135 bypass around the City of Douglas. Project included replacing an at-grade CSX  railroad crossing with a new location  4-lane bridge with a narrow median, realignment of Old Bell Lake Road on new location, stream relocation/restoration, two new bridge culverts, and four box culvert extensions in the effective floodplain.

Project included 24 side roads and 102 driveways. Several side road realignments included correcting skew angles, sight distance issues, misalignments with opposing side roads, sub-par vertical/horizontal alignments and reduced spacing from major intersections.  Responsible for roadway geometric design, railroad bridge coordination, value engineering, SUE coordination, constructability review, site distance calculations,  construction cost estimates, database coordination, cost estimates, multi-disciplinary coordination, quantity calculations, concept design and report,  public involvement meetings, preliminary plans, right-of-way design, pavement design, onsite ecology impact mitigation, stream relocation, signing  and marking plans, staging plans, onsite detour plan, erosion control/CMP design, final plans, utility plans, and use-on-construction revisions.  Additional work included aiding GDOT in set-aside litigation and discrimination lawsuits, as well as plan revisions to settle cases.

Reconstruction of Interchange at SR 3/US 19 and Turn Lanes at SR 16 in Griffin, Spalding County, Georgia

1.9 miles of compressed diamond interchange reconstruction, widening SR16 from existing 3-lane and 4-lane with flush and depressed medians to  4- lane hybrid section with 20-foot raised median, bridge replacement over SR3/US19, and bridge widening on SR3/US19 over Poplar Road. Project  also included 21 driveways and 7 intersections, replacing SR3/US19 entrance ramp with 2-lane concrete ramp for heavy truck traffic, realigning the  corresponding exit ramp, realignment of Carver Road, widening SR3/US19 with bridge widening over Poplar Street, 2 new signals, and signal timing  for 4 signals. Responsible for design/review of roadway geometric design, urban and rural drainage, bridge end-rolls, site distance calculations,  logical termini, multiple constructability reviews, limited access bridge design coordination, erosion control design, staging design, pavement design, construction cost estimates, database coordination, concept design/report, value engineering, preliminary plans, right-of-way plans, signing/marking plans, erosion control/CMP design, staging plans, utility plans, final plans, and MS4 design.

SR133 Widening from CR388/Hawthorne Road to SR35/East Moultrie Bypass, Colquitt County, Georgia

2423a.jpg

Project consisted of widening 5-miles of SR133 existing GRIP project from existing 4-lane rural to 5-lane urban roadway. Design included rolling profile to drain extremely flat existing roadway, curb/gutter, sidewalk, closed drainage, open channel drainage, public involvement, 27 side road intersection realignments, and 161 driveways.  Side road realignments included correcting skew angles, sight distance issues, misalignments with opposing side roads, and sub-par vertical/horizontal alignments.  Responsibilities included public involvement, database coordination, value engineering, SUE coordination, constructability review, preliminary plans, right-of-way plans, signing and marking, erosion control plans, comprehensive monitoring design, staging plans, pavement design, utility plans, final plans, use-on-construction revisions, and aiding GDOT in condemnation cases for several parcels.


 

Widening SR1/US27 from Turnberry Lane to SR315, Muscogee & Harris Counties, Georgia

Approximately 9 miles of widening and relocation of US 27/SR 1 from existing      two lanes to four lanes with variable median widths. Additionally, there are approximately  3.5 miles of side road relocation onto new alignments.  Conceptual alternates include several bypasses to minimize impacts to Cataula’s historic district and numerous other environmentally sensitive areas within the project corridor. The southern portion of the project includes a 5-lane urban typical section with sidewalks that transitions to a 5-lane rural section with open ditches. Because funding is limited due to TIA budget, numerous design exceptions and design variances will be utilized  to keep existing design elements as well as to provide non-standard designs. This project will include a PAR, public involvement, Rails-to-Trails coordination, and roadway design from concept phase through final design, including preliminary, right-of-way, and final roadway plan production.
