Drivers demand and deserve efficient and smooth riding on roadway systems. The challenge for the highway design engineer is to meet the public’s desire for transportation efficiency while meeting other important public interests, such as: low costs; long-lasting roads and structures; convenience; and roadway construction in harmony with the environment. And most importantly, overarching all of these principals, is the requirement of safety. 

Reilly Associates has the staff and demonstrated knowledge to incorporate these factors into our cost-effective designs. Our engineers are experienced with PennDOT Design Manuals and AASHTO design procedures and guidelines and will apply them to provide technically sound and practical solutions to your highway or bridge project. Our clients include PennDOT and the Pennsylvania Turnpike Commission as well as numerous counties, local municipalities and private industrial park developers.
