Start demolition and preparation work for new curb ramps at Fremont/Bonde, Fremont/Peralta and Fremont/Parish intersections.

Week of February 16th:

Continue demolition on the west side of Fremont Blvd and continue installation of sidewalk-level bike lane, sidewalk, and driveway improvements between Thornton Ave and Bonde Way.
Continue preparation work for new curb ramps at Fremont/Bonde, Fremont/Peralta and Fremont/Parish intersections.

Week of February 23^rd:

Continue demolition on the west side of Fremont Blvd and continue installation of sidewalk-level bike lane, sidewalk, and driveway improvements between Thornton Ave and Bonde Way.
Continue sidewalk and driveway replacement in front of AT&T Maintenance Yard on Fremont Blvd between Alder Ave and Thornton Ave.

Anticipated Traffic Impacts:

Construction activities on Fremont Blvd between Thornton Ave and Bonde Way are scheduled to begin in early January 2026. During this phase of construction, the existing outside eastbound travel lane on Fremont Blvd (toward Peralta Blvd) will be closed 24-hour/7days to accommodate sidewalk-level bike lane, sidewalk, and driveway improvements. Additional lane closures may be needed between the hours of 8:30 am and 4:00pm. All existing driveways will remain accessible. Westbound traffic lanes on Fremont Blvd (toward Decoto Road) will not be impacted during this stage of construction. Drivers are strongly encouraged to pay close attention to the posted temporary signage and striping when approaching the construction zone.

The temporary 24-hour/7day lane closures and pedestrian detours at the Thornton Ave./Fremont Blvd. intersection are still ongoing to facilitate construction at the intersection corners. Moderate delays (up to 5 minutes) can be expected between 8:30 am and 4:00 pm. The contractor will not be closing any additional vehicle lanes during the morning and afternoon commute periods. Temporary pedestrian and bicycle detours will be provided around each work area.

It is important to note that existing traffic signal sensors may be disturbed during the various construction activities, and the City will be placing affect signal phases on “manual call” as needed. This may result in motorists experiencing additional delay when there may not be conflicting vehicle traffic at traffic signals.

Motorists are advised to exercise caution when driving through construction areas or use alternate routes if possible.

Overview

The Centerville Complete Streets project will improve segments of Fremont Boulevard (Alder to Eggers), Thornton Avenue and Peralta Boulevard.

The project site is located in the heart of the Centerville commercial district and within close proximity to numerous schools, businesses, AC Transit bus lines, and the Centerville Altamont Corridor Express (ACE)/Amtrak train station. Many of the area roadways are in poor condition and were developed to old state highway standards (former State Route 84) focused on vehicle traffic with wide lanes and intersections. There are gaps in the sidewalk and bicycle lanes, and an overall lack of improvements for bicycles and pedestrians. The recent relinquishment of SR 84 allows the City to have local control over this street right-of-way to repave the streets and implement “complete streets” improvements to enhance safety and mobility for all users, including drivers, pedestrians, bicyclists, school children, and businesses.

Objectives

The project will feature significant complete streets improvements, including:

Sidewalk widening improvements and replacement
Raised and separated bikeway along Fremont Blvd between Thornton Ave. and Central Ave.
Pavement rehabilitation
Upgraded traffic signal and protected intersection at Fremont Blvd./Thornton Ave.
Upgraded traffic signal at Dusterberry Way
New traffic signal at Thornton Ave./Oak St.
New pedestrian flashing beacon at Artist Walk driveway
Transit stop enhancements
New on-street parking spaces on Fremont Blvd
Pedestrian and bicycle access/safety improvements along Thornton Avenue near Thornton Middle School. (see below)

For the area in the vicinity of the railroad crossing, future improvements will be made in conjunction with the planned Centerville Railroad Safety Improvement project.

For the area south of Peralta Boulevard, future improvements will be made in conjunction with the planned private development project (formerly Silicon Sage).

Fremont Blvd/Thornton Ave Intersection Safety Improvements

As part of the Centerville Complete Streets Project, safety improvements will be constructed at the Fremont Boulevard and Thornton Avenue intersection to enhance safety and access for all road users, including pedestrians, bicyclists, transit riders, and motorists. The Fremont/Thornton intersection experiences high pedestrian and bicycle activity as well as high vehicle traffic volumes due to the close proximity to American High School, Thornton Middle School, and local businesses at the intersection of two major regional commute corridors.

Key intersection improvements include installing new elevated and enlarged curb returns to accommodate the large number of waiting pedestrians and shorten pedestrian crossing distances; striping of high visibility crosswalks; installing new ADA-compliant curb ramps; upgrading existing bus stop areas; upgrading the existing traffic signal to improve overall signal operation and reliability; and improving existing pavement conditions.

The existing right-turn lanes in the southbound Fremont Boulevard and eastbound Thornton Avenue approaches will be preserved given the high right turn vehicle demand. The right-turn lane in the westbound Thornton Avenue approach will be removed due to low vehicle demand and to accommodate the corner pedestrian and bicycle improvements. All commercial driveways will remain open and accessible during the intersection construction. The attached exhibit illustrates the new intersection design layout.

Thornton Middle School Safety Improvements

A number of safety improvements along Thornton Avenue near Thornton Middle School will be constructed as part of the Centerville Complete Streets Project, including the construction of concrete curb extensions, high visibility crosswalks, existing sidewalk enhancements, existing traffic signal upgrade, and new striped buffered bike lanes. The project will also install a new traffic signal at Thornton Avenue/Oak Street intersection to facilitate school traffic and pedestrian crossing. Exhibits depicting the various improvement elements can be seen below. Any questions related to the school safety improvements along Thornton Avenue can be emailed to centervillecompletestreets@fremont.gov.

Community Engagement

As part of the project, the City conducted an extensive community engagement process to obtain feedback from stakeholders, including residents, businesses, transit providers, and pedestrian and bicycle groups, on the project’s design. The City hosted four community meetings, as well as obtained on-going feedback from the project website, that ultimately help to confirm the proposed project scope and design elements. The City also met separately with Thornton Middle School staff and conducted outreach to the PTSA community to inform and obtain comments from school parents related to proposed safety elements along Thornton Avenue adjacent to the Thornton Middle School campus.
