Van Buren Bridge

Replace existing northbound and southbound Van Buren bridges

Project Overview

Contractor Griffith Company
Construction Cost $25 million
Construction Start September 2009
Construction Completion Winter 2013
Work Hours Monday – Friday 7 AM – 6 PM

 

The existing Van Buren Bridges were constructed in 1939 (southbound) and 1958 (northbound) spanning the main waterway in Santa Riverbed.  These bridges were extended in length in 1971 to span the entire flood plain. In 1997, the bridges were evaluated for seismic safety, and it was determined that retrofitting of the bridges would be required. It was also concluded that a total replacement of the bridges would be the most feasible and prudent strategy.

 

 

Project Purpose and Need

The proposed project is a seismic retrofit project with the strategy of total replacement of the existing bridges.  The existing bridges are substandard in width for expressway classification in addition to their seismic deficiencies.  They lack standard shoulders, a sidewalk for safe pedestrian crossing, and adequate number of traffic lanes to accommodate expected future traffic.

To remedy these conditions, the proposed project will:

  • Provide replacement bridges of approximately 1,005 feet in length and reconstruct the 2,600 feet of approach roads.
  • Provide a state of the art structurally and seismically sound bridge in this liquefaction prone area with complementing aesthetic features.
  • Provide standard shoulders, adequate bridge width for a future third lane in each direction, and sidewalks with positive separation from vehicular traffic, thus improving the safety for pedestrians.
  • Provide traffic signal and intersection modifications, street lighting, and other pertinent improvements.

Traffic

In 2001, the average daily traffic (ADT) on the Van Buren Boulevard Bridge was 54,300 vehicles per day.  The Van Buren Boulevard is forecast to carry approximately 73,700 vehicles per day (ADT) in 2025.  The proposed project is a seismic retrofit project.  It will not result in a traffic capacity increase in conformance with the HBP-Seismic Retrofit Funding guidelines.  However, the new bridges will be built to accommodate an ultimate six lane width.  Restriping the structure to six lanes and the associated Van Buren Boulevard roadway widening north and south of the bridges will be completed under a future and separate project.

The existing traffic will be maintained through the construction area with two lanes in each direction.  The only exception will be late night closures of one lane in each direction to allow the contractor sufficient space to operate large equipment particularly during the Stage I of the construction, which is estimated to be one year three months long.  The total duration of construction is 2.5 years starting September 16, 2009.

Engineering Features

The new northbound and southbound bridges are slightly longer than the existing bridges.  The total length is 1003 ft for the southbound and 1008 ft for the northbound bridge.  The bridges are wide enough to accommodate three traffic lanes in each direction with an 8 ft wide outside shoulder and a five ft wide (clear width) sidewalk.  The sidewalks are separated from vehicular traffic with concrete barriers for pedestrian safety.  The outside shoulders are wide enough for delineation as a Class II Bike Lane in the future.

 

Construction Activities

 

March 22, 2013

Alternating lane closures on I-215 from Cactus Ave. to Harley Knox Rd.

March 25, 2013
SB/NB 9:00 p.m. – 4:00 a.m.

March 26, 2013
SB/NB 9:00 p.m. – 4:00 a.m.

March 27, 2013

March 28, 2013
NB/SB 9:00 p.m. – 4:00 a.m.

The purpose of these closures is to allow for pile excavation in the median. No detour is necessary. Flaggers will be present to assist with traffic.
