About this Project

The District 6 Open-End Safety Improvements project is part of PennDOT’s Highway Safety Improvement Program (HSIP), targeting intersections and corridors throughout southeastern Pennsylvania to reduce crash rates and enhance traffic safety. The program addresses various locations, including roundabouts, signalized intersections, and corridor improvements, to enhance operational efficiency, improve pedestrian and cyclist safety, and enhance overall roadway function. Some intersections are complete, while others remain in the design or construction phases, reflecting the ongoing nature of the district-wide initiative.

AEG’s scope includes comprehensive geotechnical engineering and survey services for multiple intersections and corridors. AEG conducts field surveys under the direction of licensed professional land surveyors, establishing horizontal and vertical control networks, collecting topographic data, and preparing digital terrain models for design purposes. The team researches right-of-way, property ownership, and prepares Notice of Intent to Enter letters for affected parcels, ensuring compliance with PennDOT’s Design Manual and facilitating property acquisition as needed.

Geotechnical investigations are a core component of AEG’s work. Our team prepares Subsurface Exploration Planning Submissions (SEPS), coordinates and supervises test borings, and performs laboratory testing on soil and rock samples in AEG’s certified lab. These investigations inform pavement design, stormwater management, and foundation recommendations for roundabout and intersection improvements. AEG also supports infiltration testing and stormwater management design, ensuring that each project meets regulatory requirements and minimizes environmental impacts.

Throughout the program, AEG provides construction consultation, assists with utility coordination, and prepares maintenance and protection of traffic plans. The firm’s multidisciplinary expertise enables seamless integration of geotechnical and survey data into the design process, supporting PennDOT’s mission to deliver safer, more efficient transportation infrastructure across District 6-0.
