S.R. 0095 Section CPR, Delaware Expressway, Philadelphia County
AEG provided design and construction consultation services to reconstruct about 1.4 miles of S.R. 0095 in Philadelphia County, Pennsylvania from Levick Street north to the State Road Viaduct, including the reconfiguration of the Cottman and Princeton Avenue modified directional interchange complex. The project includes widening the S.R. 0095 mainline to four continuous lanes by direction and eliminating the lane drops within the interchange complex, eliminating the southbound entrance ramp from Princeton Avenue, constructing two new southbound entrance ramps, realigning other existing exit and entrance ramps, and providing numerous off-route improvements. AEG provided survey, geotechnical, pavement, hazardous materials, and roadside development services. AEG coordinated and calibrated aerial surveys. AEG also performed all the supplemental topographic surveys and boring stakeout for the corridor. AEG developed the digital terrain model used for project design. AEG developed and performed all the soils and geologic investigations for the project, which included, in part: 7 mainline structure replacements, widening of 16 spans of the State Road Viaduct, 16 retaining walls, and numerous overhead sign structures and other facilities. AEG performed foundation designs for the Viaduct widening, 11 retaining walls, sign structures, and other facilities, and assisted others for the remaining geotechnical designs. AEG performed all the mainline and off-route pavement designs, including life cycle cost analyses. High performance concrete pavement specifications were adopted for this project. AEG assisted in developing Phase II and Phase III Environmental Site Assessments and performed hazardous materials field sampling on behalf of others. AEG developed and implemented disposal protocols for contaminated soils encountered during the subsurface explorations. AEG is currently performing all hazardous materials construction submissions reviews for the CP2 project. AEG, working with others, provided Roadside Development Plans for the corridor, including streetscape, pocket park and other local improvements. AEG is providing on-going construction consultation services for these work items for the project corridor.
