Sierra Avenue (Foothill Boulevard to Baseline Avenue) Street Improvement Project
Project Description
The City of Fontana has begun studies to widen and make improvements to Sierra Avenue between Foothill Boulevard and Baseline Avenue. The project proposes widening this section of Sierra Avenue from two lanes to three lanes in each direction, adding turn-lanes, upgrading traffic signals, and improving the intersections of Sierra Avenue/Foothill Boulevard and Sierra Avenue/Miller Street. Other improvements are also proposed, including new sidewalks, street lighting, bicycle lanes, and curb ramps to meet Americans with Disabilities Act standards. A raised landscaped center median also is proposed for this area.  Sierra At Foothill

Project Benefits
Sierra Avenue is one of the City of Fontana’s major north-south transportation corridors. The proposed Sierra Avenue Street Improvement Project would offer the following benefits:
  • Improved North-South Access: The existing four-lane road is at capacity and will not be able to handle future forecasted traffic. The project would improve access between downtown Fontana and north Fontana and the State Route 210 corridor by widening this section of Sierra Avenue from two lanes to three lanes in each direction.
  • Enhanced Traffic Flow: Many parts of Sierra Avenue do not have a median refuge to make left turns. Vehicles turning left at intersections and into driveways can cause traffic congestion during peak hours and increase the chance of rear-end collisions. The project would add left-turn lanes and upgraded traffic signals at the intersections of Foothill Boulevard, Miller Avenue and Baseline Avenue. The project also meets the City’s Master Plan for Circulation in this area, which identifies this section of Sierra Avenue as a “Modified Major Highway.” Please click here to view the City’s Master Plan for Circulation. 
  • Upgraded Connectivity and Accessibility: Many parts of the project area do not have sidewalks, while other areas have sidewalks, but they are not connected. Some existing sections of sidewalks are uneven or buckled, which limits accessibility for pedestrians, particularly for seniors, those with disabilities, and those using wheelchairs. This section of road also does not have bicycle lanes. Many intersections do not have curb ramps. Where curb ramps exist, many need to be upgraded to meet current Americans with Disabilities Act (ADA) standards. The project would add continuous concrete sidewalks, bicycle lanes, and standardized curb and driveway ramps on both sides of Sierra Avenue to improve connectivity through the area and promote active modes of transportation. (Should we provide a link to the City of Fontana’s Active Transportation Plan that is on the website? http://www.fontana.org/index.aspx?NID=2717)
  • Beautification: Landscaping in this area is minimal and does not have a theme to build community pride. A raised, landscaped median is proposed to beautify the area and reduce points of conflict for left-turn and U-turn movements.

Anticipated Project Schedule

Engineering and Environmental Studies began in mid-2016.  Engineering studies will help the City of Fontana analyze alignment alternatives.  Environmental studies will identify possible effects to the area and ways to minimize those effects.  Project construction is currently scheduled to begin in 2018.  At this time, work hours, detours, and construction schedule details have not been determined.
