 183 North

 Mobility 

 Project  

CP&Y was the prime consultant to prepare schematics, environmental documentation, and conduct public involvement for this high-profile, 13-mile project to construct two managed lanes in each direction in the median of US 183 from SH 45 North to State Loop 1.

 

The project included a schematic design for 13 miles of express lanes and four miles of additional general purpose lanes in each direction, including direct connectors at two interchanges and identification of ingress/egress locations between the general purpose lanes and express lanes based on origin and destination data and traffic simulations.

 

The purpose of this $381 million project was to facilitate congestion management, provide a reliable route for transit, and facilitate reliable emergency response. Cost savings or efficiency in operations: Maintained existing pavement and bridges through design exceptions and use of appropriate design speeds. Maintained initial schedule despite two major design changes that occurred during project development, including the expansion of the project from adding one express lane in each direction to the addition of two express lanes in each direction.

 

Public involvement efforts started at the end of 2013 and continued until early 2016. Public involvement and community outreach milestones included three live Open Houses, three virtual Open Houses, multiple Technical Workgroups, and a final live Public Hearing and virtual Public Hearing over the course of three years.

 

The team was responsible for educating, gathering, and integrating public input and data from these meetings and workgroups to take into consideration when developing the final preferred alternative. The team collected data and public comments on a variety of project aspects such as the purpose and need, the problems the Client is trying to address and consider, context sensitive solutions, and bike/ped improvements and additions.

 

Alternatives evaluated during this process were General Purpose Lanes, Express Lanes, High Occupancy Vehicle (HOV) Lanes, Transportation System Management, and Transportation Demand Management (TDM). During this extensive process, the team was responsible for creating and presenting multiple pieces of an integrated campaign as seen on the attached collateral sheet. The team prepared a Public Hearing Summary and Analysis Report as well as the final Environmental Assessment document for an environmental decision.

 

As a result of heavy public involvement, a fourth general purpose lane was added where there are currently three. Maintaining the initial schedule was accomplished through weekly consultant team phone calls and regular schedule updates to identify opportunities for schedule recovery.
