Three alternatives were studied by SBCTA as part of the I-10 Corridor Project.

Alternative one: no build

This alternative looked at what might happen if nothing is changed—no additional travel lanes or ramp improvements would be constructed.

Alternative two: HOV Lane

The addition of one HOV/Carpool Only Lane in each direction of I-10 between Haven Avenue in Ontario and Ford Street in Redlands (25 miles).  The number of General Purpose Lanes would not be changed.
