CRIADO was responsible for the preparation of schematic roll plots for proposed overhead guide signs and Subsurface Utility Engineering (SUE) services on SL 335(approximately 40 miles) from a conversion of non-freeway, to a freeway design. The project included grade separations on intersecting cross streets, frontage roads, ramps, and four general-purpose lanes created to accommodate six lanes in the City of Amarillo, Texas. The design also involved the reconstruction of existing interchanges of US 87 and IH 40 with SL 335 consisting of a frontage road system and a proposed 3- level grade separation of the main lanes.
