 Motorists traveling eastbound at the eastern terminus can exit to Clay Street, Dallas Street, I-45 northbound, or I-45 southbound.The ramp from eastbound Allen Parkway to southbound I-45 was known by long-time Houston residents as one of the most difficult in the Houston area, with a blind merge into the far left lane.However, this ramp was relocated to enter I-45 south from the right as of January 2017.
