The group assisting Mayor Lee Leffingwell with planning Austin's next high-capacity transit, or HCT, investment will evaluate the final transit modes and route options in March and April.

In May, members of the Central Corridor Advisory Group will review the locally preferred alternative for a transit route in the subcorridor, cost estimates and options to phase the project.

In June, CCAG will propose a transit project to Austin City Council, which will consider putting a bond on the Nov. 4 ballot.

The Central Corridor is part of the Project Connect regional transportation plan and is roughly bounded by Koenig Lane, Springdale Road, Oltorf Street and MoPac. In December, City Council approved a subcorridor to focus HCT between Highland Mall and East Riverside Drive.

To choose the final options, the Project Connect planning team created a service profile that incorporates the community's priorities. The team used input from community meetings and online surveys, said Scott Gross, urban rail program manager with the city of Austin's Transportation Department.
