Fast Forward: Delivering a Better Commute
on the 91 in Riverside County

 

The Riverside County Transportation Commission (RCTC) and project partners are making improvements to the 91 from Corona to Riverside. Construction began in early 2014 and new lanes are expected to open in 2017.

The project is divided into 10 key segments along the 91 and south on Interstate 15. Mouse over the Segment Locator Map to view the detailed segment map. To visit a segment detail page, simply click on the map in the viewer or use the main menu above.

County Line To Green River Road | Segment Highlights

  • State Route 91 narrows near the Orange County/Riverside County Line, with the Cleveland National Forest to the south and the Santa Ana River to the north.
  • Two Tolled Express Lanes will be built in both directions between the County Line and Interstate 15, replacing the existing single carpool lane in both directions.
  • The 91 Project will provide an access opening and add a new lane within the existing median at the County Line. This new lane will be added between the Tolled Express Lanes and the regular lanes to help drivers enter and exit the Tolled Express Lanes.

Green River Road to State Route 71 | Segment Highlights

  • Two Tolled Express Lanes will be built in both directions between the County Line and Interstate 15, replacing the existing single carpool lane in both directions.
  • The westbound on-ramp and off-ramp at Green River Road will be adjusted to fit the newly widened 91.
  • The westbound off-ramp alignment will be improved with a new railroad overhead bridge.

State Route 71 to Serfas Club Drive/Auto Center Drive | Segment Highlights

  • Two Tolled Express Lanes will be built in both directions between the County Line and Interstate 15, replacing the existing single carpool lane in both directions.
  • One regular lane will be built in both directions from the 71 to Interstate 15.
  • Connecting ramps and lanes between State Route 91 and State Route 71 will be modified as part of the 91 Project:
  1. The connector from southbound 71 to westbound 91 will be realigned.
  2. The connector from southbound 71 to eastbound 91 will be widened.
  3. The connector from westbound 91 to northbound 71 will be adjusted.

Serfas Club Drive/Auto Center Drive to Maple Street | Segment Highlights

  • Two Tolled Express Lanes will be built in both directions between the County Line and Interstate 15, replacing the existing single carpool lane in both directions.
  • One regular lane will be built in both directions from the 71 to Interstate 15.
  • The westbound on-ramp and the eastbound off-ramp to and from Serfas Club Drive/Auto Center Drive will be maintained and adjusted slightly.
  • The eastbound on-ramp from Serfas Club Drive/Auto Center Drive will be rebuilt to cross beneath the eastbound off-ramp to Maple Street. Existing Frontage Road south of the 91 that connects Serfas Club Drive and Maple Street will be realigned and moved further south to provide room for the new 91 lanes and ramps.
  • The westbound on-ramp from Maple Street will become a western extension of Sixth Street south of the 91, with a flyover ramp that will merge with the new lanes.
  • The existing eastbound on-ramp from Maple Street will be replaced by a hook on-ramp that will begin at Sixth Street opposite Paseo Grande.

Lincoln Avenue to Grand Boulevard | Segment Highlights

  • Two Tolled Express Lanes will be built in both directions between the County Line and Interstate 15, replacing the existing single carpool lane in both directions.
  • One regular lane will be built in both directions from the 71 to Interstate 15.
  • The Lincoln Avenue westbound on-ramp and off-ramp will be changed to a tight diamond shape, eliminating the existing hook ramps.
  • The Lincoln Avenue eastbound on-ramp and off-ramp will be similar to the existing condition, but will change to hook ramps to connect to the newly extended D Street east of Lincoln.
  • The existing westbound on-ramp and eastbound off-ramp to and from Grand Boulevard are very close to the Lincoln Avenue ramps, causing traffic flow problems. To correct this, the Grand Boulevard ramps will be removed and replaced with new frontage roads that will connect to the Lincoln Avenue interchange ramps.
  • North of the 91, Bollero Place will be extended east to connect to West Frontage Road, which continues to Grand Boulevard. This new frontage road will be shifted north to accommodate the new lanes and ramps.
  • South of the 91, D Street will be extended east to connect to 2nd Street at Buena Vista Avenue, and then continue to Grand Boulevard.

Main Street to Interstate 15 | Segment Highlights

  • Two Tolled Express Lanes will be built in both directions between the County Line and Interstate 15, replacing the existing single carpool lane in both directions.
  • One regular lane will be built in both directions from the 71 to Interstate 15.
  • The westbound on-ramp and eastbound off-ramp on the west side of Main Street will be maintained and adjusted slightly to allow for the 91 widening in each direction.
  • Diamond interchange ramps will be added on the east side of Main Street, but the Main Street eastbound on-ramp and westbound off-ramp to and from the Interstate 15 (I-15) connectors will include a new "collector-distributor road" to collect vehicles and separate them from 91 traffic. This new road will eliminate the need for vehicles to weave and merge between the 91 and I-15.
  • Drivers using the eastbound Main Street on-ramp to the 91 will split from I-15 drivers by traveling under the new collector-distributor road mentioned above before merging onto eastbound 91.
  • Drivers using the westbound 91 off-ramp to Main Street will exit onto the new collector-distributor road and merge with vehicles from the I-15 connectors before exiting onto Main Street.
  • The connector from northbound I-15 to westbound 91 will be widened to two lanes where it merges with the new westbound collector-distributor along the 91.
  • A new tolled express lane direct connector will be constructed to and from the 91 tolled express lanes to new tolled express lanes in the median of I-15 south of the 91.

Interstate 15 to McKinley Street | Segment Highlights

  • A new eastbound regular lane will be added to the 91 east of Interstate 15 by restriping the lanes without widening the existing roadway. This new lane will continue through the McKinley Street interchange and end at the Pierce Street eastbound off-ramp.

McKinley Street to Pierce Street | Segment Highlights

  • A new eastbound regular lane will be added to the 91 east of Interstate 15 by restriping the lanes without widening the existing roadway. This new lane will continue through the McKinley Street interchange and end at the Pierce Street eastbound off-ramp. This segment marks the eastern end of the project.

Interstate 15: 91 to Magnolia Avenue | Segment Highlights

  • A new tolled express lane direct connector will be built to and from the 91 tolled express lanes to new tolled express lanes in the median of I-15 south of the 91.
  • One southbound express lane and one northbound express lane will be built in this area.

Interstate 15: Magnolia Avenue to Ontario Avenue | Segment Highlights

  • A single tolled express lane in each direction will extend in the median of I-15 from the 91 direct connector to south of Magnolia Avenue.
  • Traffic entering or exiting I-15 at Ontario Avenue and points south will be able to use the direct connector to or from the 91 tolled express lanes.

OVERVIEW

The 91 in Riverside County ranks among the nation's worst commutes. Stop-and-go traffic is the norm, especially during morning and late afternoon rush hours. In fact, traffic congestion on eastbound 91 between Anaheim and Corona is routinely among the worst five areas in the nation.

Good news is on the way for drivers, thanks to the 91 Project. Led by RCTC, the project will add regular lanes, tolled express lanes, auxiliary lanes and direct express lane connectors from the northbound 15 to the westbound 91 and from the eastbound 91 to the southbound 15. Improvements to interchanges, ramps and surface streets also will be made along the 91 corridor. Please go to Project Segments for more detailed information.

These improvements will reduce delays, allow faster emergency response, relieve local street congestion and offer better access to public transit and trails, all of which will allow motorists to "Fast Forward" their travel. In addition, this innovative design-build project is creating 16,200 jobs. Please go to Project Benefits for more information.
