There are two alternatives being studied by SBCTA as part of the I-15 Corridor Project.
This alternative looks at what might happen if nothing is changed – no additional travel lanes or ramp improvements would be built.
The addition of two Express Lanes in each direction between SR 60 and SR 210 and the addition of one Express Lane between SR 210 and Duncan Canyon Road. Motorists may choose to pay a toll to travel faster on the Express Lanes, with carpools enjoying free or reduced travel depending on congestion. The number of General Purpose Lanes would not be changed.
