As part of the Austin Transit Partnership Project Connect, the Blue Line route will connect to the Orange line near Republic Square and travel through a tunnel under 4th and Trinity Street with a stop at the Convention Center. The route will then transition to a new dedicated bridge crossing Ladybird Lake, then turn east along East Riverside Drive, crossing IH-35, US-71, and US-183, running alongside US-183 to US-71, then alongside US-71 to Austin-Bergstrom International Airport (AUS).
