I-5 Corridor Improvement Project (US 50 to Sac/Yolo County Line)
The I-5 Corridor Improvement Project proposes to construct managed lanes on both directions on Interstate 5 (I-5) in Sacramento County from the I-5 and US 50 Interchange to the Sacramento River Bridge and the Sacramento-Yolo County line. The purpose of the project is to reduce congestion, increase the number of people traveling through the area, provide multimodal access, promote ride sharing, improve mobility and improve traffic operations through added intelligent transportation system infrastructure. The proposed project has evaluated six alternative types of managed lanes to accomplish the purpose of the project.
Description and Location
The project proposes to construct managed lanes in both directions on Interstate 5 (I-5) in Sacramento County from I-5/US 50 Interchange to Sacramento River Bridge (Br No 22-0025). Intelligent transportation system (ITS) infrastructure will also be added to actively manage recurrent and non-recurrent congestion.
Project Alternatives
No Build: The interstate would not change and the project would not be constructed.
Build Alternative 2: high occupancy vehicle (HOV) lane in each direction for use by vehicles with two or more riders in each direction.
Build Alternative 3: Add a High-Occupancy Toll (HOT) Lane for use by vehicles with two or more riders in each direction.
Build Alternative 4: or more people to use the lane for no charge, while single occupancy vehicles (SOV) and vehicles occupied by 2 people would pay a toll to use the lane.
Build Alternative 5: where everyone using the lane pays to use the lane, regardless of number of riders.
Build Alternative 6: for use by only transit vehicles.
Build Alternative 7: Repurpose the current #1 general-purpose lane to HOV 2+ between I-5 at SR-50 and the Del Paso Interchange. No new travel lanes would be constructed north of the general-purpose lane conversion; however, other improvements discussed below would be included north of the lane conversion.
