City Council Memorandum
TO: HONORABLE MAYOR AND CITY COUNCIL DATE: JANUARY 13, 2026 FROM: PUBLIC WORKS DEPARTMENT WARD: 1
SUBJECT: AMENDMENT NO. 1 TO THE SERVICE AGREEMENT BY AND BETWEEN COUNTY OF RIVERSIDE, CITY OF JURUPA VALLEY, AND CITY OF RIVERSIDE FOR MISSION BOULEVARD BRIDGE IMPROVEMENTS AT SANTA ANA RIVER, IN THE AMOUNT OF $3,975,276 FOR A NEW TOTAL CONTRACT AMOUNT OF $5,208,186 ISSUE:
Approve Amendment No. 1 to the Service Agreement by and between the County of Riverside, City of Jurupa Valley, and the City of Riverside for the Mission Boulevard Bridge Improvements at the Santa Ana River.
RECOMMENDATIONS:
That the City Council:
Approve Amendment No. 1 to the Service Agreement by and between the County of Riverside, City of Jurupa Valley, and the City of Riverside for Mission Boulevard Bridge Improvements at Santa Ana River, in the amount of $3,975,276, increasing the total agreement amount to $5,208,186; and Authorize the City Manager, or designee, to execute Amendment No. 1 to the Service Agreement by and between County of Riverside and City of Jurupa Valley and City of Riverside, including making minor and non-substantive changes, subject to availability of budgeted funds.
BACKGROUND:
The existing Mission Boulevard Bridge over the Santa Ana River is an important transportation link between the City of Riverside and the City of Jurupa Valley (Cities). This existing 11–span concrete girder bridge was constructed in 1958 and is over 1,100 feet long.
In April 1997, the County of Riverside (County) initiated a seismic assessment of the existing bridge. After an analysis and considering the high potential for bridge site soil liquefaction, the County and the California Department of Transportation (Caltrans) agreed that a total replacement of the structure was the appropriate seismic retrofit alternative. Subsequently, Federal funding was allocated under the Highway Bridge Program (HBP) to completely reconstruct the Mission Boulevard Bridge with the Cities being proportionally responsible for the matching fund requirements under the HBP. The Project also received State Seismic Bond Funds (Prop 1B) to assist both Cities with the local match funding requirement.
On June 16, 2015, the City Council approved a three-party Service Agreement with the County of Riverside and the City of Jurupa Valley to design and reconstruct the Mission Boulevard bridge over the Santa Ana River between the Cities. Because the County of Riverside initiated the project prior to the City of Jurupa Valley being incorporated and because the County has extensive experience administering bridge projects under various Federal bridge programs, the Service Agreement provided that the County act as the lead agency to administer the work.
The Service Agreement also defined the local match funding responsibilities for the Cities based on the portion of the project lying within each jurisdiction. The City of Riverside is required to contribute 57% of the local match funding, while the City of Jurupa Valley is responsible for 43%. After the allocation of the Prop 1B funds towards the local match responsibility, the Service Agreement required that the City of Riverside contribute $1,232,910 and the City of Jurupa Valley contribute $930,090.
On January 23, 2017, the City Council authorized the Community and Economic Development Director to sign a concurrence letter for the proposed Mission Boulevard Bridge aesthetics. Some of the elements selected include Fractured Ribbed Abutments; Belvederes; Mission Arch Design and Railings; Decorative Entry and Interior Pilasters; and Multi-purpose Trail Lighting.
On July 24, 2019, Caltrans determined the project had no significant impacts on the environment as defined by the National Environmental Policy Act and the project received an approved Categorical Exemption / Categorical Exclusion Determination Form. However, the project requires necessary permits from various environmental agencies prior to commencement of construction which has taken several years to secure.
DISCUSSION:
The proposed Mission Boulevard Bridge Improvements at the Santa Ana River (Project) will be approximately 88 feet wide and 1,127 feet long (Attachment 1). The new bridge will not increase vehicular capacity, but the new bridge will be wider to accommodate two 14-foot traffic lanes, two 12-foot traffic lanes, two 8-foot shoulders, and a 4-foot concrete median separating the traffic in each direction. A 12-foot-wide multi-purpose trail with a concrete barrier separation from vehicular traffic will be located along the south side of the bridge in lieu of standard sidewalks on each side. The replacement bridge profile will be raised approximately 5 feet at mid-span to accommodate current roadway design standards. Deep foundations will be used to support the new bridge, consisting of 5 bents, each with 4 columns 7-ft in diameter on 8-ft diameter cast-in-drilled hole concrete piles.
The proposed Project alignment will join with the existing Mission Inn Avenue in the City of Riverside at Scout Lane adjacent to Carlson Park and will join the existing Mission Boulevard in the City of Jurupa Valley at Crestmore Road. The southern edge of the new bridge deck will remain at its current position. The widening on the northern edge will accommodate the new roadway geometrics which will minimize impacts near Carlson Park and allow for staged construction. This widening will require retaining walls along the northern right-of-way within both cities. The approaching roadways within both cities will be reconstructed to align with the new bridge decks including new striping and utility relocations.
The proposed multipurpose trail will provide pedestrian and recreational cycling connectivity along the south side of the new Mission Boulevard Bridge to the Santa Ana River Trail through Carlson Park. An existing sidewalk along the south side of Mission Boulevard starts at Crestmore Road and extends through the existing bridge and terminates at Carlson Park in the City of Riverside. Therefore, the proposed multipurpose trail will improve the current patterns by allowing both directions of pedestrian and recreational bicycle travel on the south side of the bridge only.
No sidewalk connectivity currently exists along the north side of Mission Boulevard within the project limits. Providing a new sidewalk on the north side of the bridge was not recommended as there are no plans to continue the pedestrian path west or east of the bridge along the north side.
The Project may require a few short-term (partial day) closures to facilitate the project staging and construction. Construction will occur in stages to allow for continued traffic flow and pedestrian access at all times. Stage 1 construction will build the northerly half of the new bridge along the north edge of the existing structure while traffic is maintained on the existing bridge. Stage 2 will shift the traffic to the newly constructed bridge, while the existing bridge is demolished and the remainder of the new bridge is constructed to the south.
The existing Santa Ana River Bike Trail (Trail) will remain in its current location during and after the new bridge construction. However, the Trail profile will be modified to provide adequate clearance beneath the bridge and meet current standards. Temporary closures will be minimized to complete the required Trail modifications, and the public will be notified well in advance for any required route detours.
The Army Corp of Engineers Levee Rehabilitation Project is currently under construction to improve the existing levees in the vicinity of the Project area. The bridge improvements will not negatively impact the Santa Any River or the existing levees. However, the Project improvements will be coordinated with the Army Corp of Engineers so neither project is negatively impacted.
On August 26, 2025, the County advertised the Project on the County’s procurement website as Bid No. B3-0528. Prior to bid opening, a mandatory pre-bid meeting was held on September 24, 2025, and six (6) addenda were issued for this advertisement. On October 16, 2025, the County received five (5) bids for the construction of the Project. The lowest responsive bid was from Skanska USA, Inc. in the amount of $58,882,197.00, which is 12.5% over the County’s Engineer’s Estimate as outlined in Table 1. The County awarded the construction contract to Skanska USA on December 16, 2025.
