TxDOT Houston IH 45 at Broadway Schematic Design
Walter P Moore has been selected by the Texas Department of Transportation Houston District to provide preliminary engineering services for the development of a schematic design layout for the interchange of IH 45 South (Gulf Freeway) at Broadway and Park Place Boulevard, currently operating as a modified roundabout with traffic signals. Considerations include an existing overpass with low clearances and a large number of support columns restricting lane configurations. The project includes an Environmental Assessment (EA) Document, public involvement, traffic engineering and operations including traffic simulations and 3-D modeling, and surveying and mapping. The work is currently underway.
Walter P Moore has evaluated Level-of-Service for the existing and proposed conditions and performed an Origin and Destination Study. We created 6 Conceptual Alternatives, to be refined into 3 Viable Alternatives and 1 Recommended Alternative. The project also includes a Preliminary Drainage Study and an Interstate Access Justification Report (IAJR) for the Recommended Alternative.
