I-8 Corridor Study

Interstate 8 (I-8) serves as one of the primary east/west travel corridors within the City of San Diego and as a key interregional corridor to the east.

SANDAG, in collaboration with Caltrans, the City of San Diego, the Metropolitan Transit System, and other key stakeholders, is developing a multimodal corridor study for I-8 within the City of San Diego. The scope of the study includes:

• Right-of-way constraints
• Transit services
• Freeway interchanges
• Selected local streets and intersections
• Bike and pedestrian access (active transportation)
• Transportation Demand Management
• Transportation Systems Management
• Other strategies to encourage the use of alternative travel modes

The corridor study will consider future improvements, as well as other feasible concepts. The study will describe existing conditions, identify future deficiencies, develop multimodal alternatives and measures, perform technical analysis, and propose an implementation strategy.

Public Meetings

Two public meetings were held in July 2014 to allow the public to weigh in on ways to improve traffic flow, transit services, and pedestrian and bike access along the I-8 freeway, interchanges, local roads, and intersections.
