I-210 Alder Ave Interchange Improvements Project

 The City of Rialto has experienced substantial growth with new developments near the I-210/Alder Avenue Interchange. The project will maintain the existing diamond interchange configuration, widen the eastbound (EB), westbound (WB) off-ramps and improvements to Alder Avenue. The improvements will enhance safety, remove existing bottlenecks, and accommodate future growth and development.

 The project improvements include:

• Eastbound off-ramp at Alder Avenue will be widened (outside) to add an additional left-turn lane, a portion of the intersection will be reconstructed and a retaining wall.
• Westbound off-ramp at Alder Avenue will be widened (outside) to add an additional left-turn lane, a portion of the intersection will be reconstructed.
• Northbound and Southbound Alder Avenue will be widened, a curb ramp, retaining wall, a pedestrian island will be constructed.
• A right-turn only lane on Southbound Alder Avenue to Westbound on-ramp at Alder Avenue will be constructed.
• An additional left-turn lane on Northbound Alder Avenue onto the westbound on-ramp at Alder Avenue will be constructed. 

WHAT TO EXPECT

• Cones or other traffic control devices will be used to separate work areas from traffic. 
• Construction noise due to equipment back-up alarms and crews’ voices. 
• Water trucks will be used to maintain dust control during construction.
• Restrictions
  • Lane restrictions on Alder Avenue bridge.
  • Lane shifts on Alder Avenue and freeway ramps.
  • Freeway on-and off ramp closures. 

Drive with caution throughout the project area and allow extra time to reach your destination.
