SAC 5 Corridor Enhancement Project


DESCRIPTION

The SAC 5 Corridor Enhancement Project (03-0H10U) in Sacramento County on Interstate 5 (I-5) from 1.1 mile south of Elk Grove Boulevard Overcrossing (PM 9.7) to American River Viaduct (PM 24.9) will rehabilitate pavement and other related assets, construct new High Occupancy Vehicle (HOV) lanes, install new fiber optic lines and extend the I-5 northbound #1 lane to improve the onramp merge and weave movement.

The proposed work includes:

  • Rehabilitate 67 lane miles of mainline and all ramps/connectors with a 40-year pavement service life. Additionally, the project includes operational improvement that is achieved by adding auxiliary lanes and extending acceleration and deceleration lanes. This will increase the weaving time and reduce impacts to traffic. Many on-ramps, off-ramps, and connectors on this I-5 segment have less than optimal transition/weaving distances for vehicles entering or exiting the freeway to accelerate and/or decelerate to match the speed of other traffic. These operational Improvements are needed because traffic merging onto and exiting from I-5 causes congestion and delays. The improved operational behavior will also reduce the potential for collisions. Congestion delays are increasing annually, so improving and adding tools to manage traffic volumes as efficiently as possible is as important as maintaining pavement integrity.
  • Replace the Casilada Way Pedestrian Overcrossing (POC) to meet current Americans with Disabilities Act (ADA) standards.
  • Update curb ramps to meet current ADA standards.
  • Construct eight new maintenance vehicle pullouts and update the gore paving at 24 ramps to reduce maintenance worker exposure to live traffic and improve worker safety.
  • Add new 23 lane miles of HOV or bus/carpool lanes.
  • Construct two new sound walls (0.7 mile) near Freeport Blvd and Pocket Road
  • Extend I-5 northbound #1 lane by 650 feet to the south to improve the on-ramp merge/weave section.


PROJECT BENEFITS

The purpose of the roadway rehabilitation project is to extend the service life of the pavement, reduce maintenance expenditures, provide improved traffic operations tools, and improve ride quality for the traveling public. It is also intended to recycle existing concrete pavement and other materials onsite to reduce waste and cost, minimize truck haul trips, and reduce the need for new aggregates and other construction materials through the use of long life pavement technology. The project is needed because the existing concrete and asphalt pavements have deteriorated and have a poor ride quality that requires annual maintenance to repair and maintain. Most of the roadway on I-5 within the project limits was constructed in the 1970’s.

The purpose of the HOV Lanes project is to relieve congestion by promoting ride sharing and the use of high occupancy vehicles such as carpools, vanpools and express bus services, and to promote bicycle and light rail as the other modes of choice during peak period travel. The HOV Lanes project will decrease peak period delay and improve system reliability for HOV and general purpose lanes users. This project will also benefit transit ridership/ ridesharing by providing less delay and a more reliable traveling option and air quality is expected to improve due to decrease in delay and vehicle miles traveled (VMT). The HOV lanes are needed because the I-5 corridor between Beach Lake Bridge at Morrison Creek and US-50 interchange is experiencing recurring congestion during peak commute periods. Traffic demand during commute periods exceeds the freeway capacity, and the amount and duration of congestion is expected to increase in the future as suburban development in portions of Sacramento and Elk Grove.
