SPUI comes to Texas
Rendering of SPUI on US 75 at Parker Rd. in Plano
Work is underway on the North Central Expressway at Parker Rd. in the Dallas suburb of Plano on what, to my knowledge, will be Texas’ first Single Point Urban Interchange, or SPUI (pronounced “spoo-ee”). (If anyone knows of an existing one in Texas, please post it!) Popular in several other states, a SPUI is a type of intersection between a surface street and a freeway’s entrance and exit ramps.
