From simple roadway or sidewalk design projects to complex highways and interchanges, GPI continues their outstanding reputation started by Beecher Greenman and Bert Pedersen. Highway design has evolved over the years with CADD and 3D design, yet our underlying principles have remained the same: highly trained engineers designing quality work to satisfy their client needs. With a growing focus on multi-modal accommodations and complete streets design, our engineers are incorporating additional elements into the designs such as bicycle lanes, bus rapid transit facilities and enhanced pedestrian zones.
