BRT Station Freeway Level Platform Design
The BRT station platform at the freeway level is expected to serve 90-100 buses on I-35W in the peak direction during the peak hour (northbound in the morning and southbound in the afternoon). An additional 25 buses will be served in the reverse direction during the peak hour. BRT service on I-35W will also provide all-day transit service to the Lake Street station. This station will provide connections to bus service operating on Lake Street as well as transit access to the entire Lake Street area from the regional routes operating on I-35W.
MnDOT and Metro Transit evaluated numerous variations of three BRT station platform design alternatives at the freeway level including a Shared Center Platform (similar to the 46th Street BRT station), a Split Platform, and an Off-set Split Platform. Factors analyzed included traffic safety, right-of-way requirements, bus capacity, transit passenger comfort and safety, user orientation for making connections, user access, bus operations, and maintenance including snow removal. It was determined that all BRT station platform design alternatives could be constructed within the same amount of right-of-way. With input from the Project Advisory Committee (PAC), MnDOT and Metro Transit selected the Split Platform option as the BRT station platform configuration that would provide the safest option for both transit riders and I-35W traffic, would provide the most efficient bus operations, and would allow for the easiest maintenance and snow removal.
