Drake Haglan & Associates is honored to receive the ACEC 2019 Engineering Excellence Award for Category C Structural Systems on the 11th Street East Tracy Overhead Bridge Replacement Project

The 11th Street East Tracy Overhead Bridge, located in Tracy California, was originally constructed in 1960. In October 2004, Caltrans classified the bridge as “Structurally Deficient,” with a Sufficiency Rating of 49.7 making the bridge eligible for replacement under the Federal Highway Bridge Program (HBP).

In 2018, the opening of the newly completed bridge marked the conclusion of a multi-year journey that included extensive coordination with multiple stakeholders and regulatory agencies.  Drake Haglan & Associates (DHA) take pride in leading the design efforts and is honored to be awarded the 2019 Engineering Excellence Award for Category C Structural Systems Award for the 11th Street East Tracy Overhead Bridge Replacement Project by the American Council of Engineering Companies (ACEC).

The new bridge provides for wider traffic lanes, 8-foot wide shoulders which also serve as Class II bicycle lanes, and barrier-separated mixed-use paths that promote the safe use across the Union Pacific Railroad (UPRR) tracks by pedestrians and bicyclists. The new bridge will also stimulate sustainable growth and development on the east side of the tracks since it will promote the use of alternative modes of transportation to access downtown Tracy. The bridge is located approximately ½ mile east of Tracy High School, allowing students that live on the east side of the UPRR tracks to safely walk and bike to the high school.

The superstructure of the replacement bridge consists of a cast-in-place, post-tensioned concrete box girder. The bridge is a single-span structure with an overall bridge length of approximately 291-feet. The girders are skewed relative to the centerline of the roadway such that the actual span length of the girders is approximately 200-feet. The bridge configuration accommodates a planned aerial intersection for a future extension of MacArthur Drive shown in the City’s General Plan. The 40- foot tall abutments are designed as free-standing bents with a mechanically stabilized earth (MSE) wall directly behind the abutments so that there is no lateral load on the abutments.

This project involved significant coordination with Caltrans since 11th Street is a principal arterial on the National Highway System. The 11th Street East Tracy Overhead Bridge is also a high-cost bridge project as the construction costs exceeded $20 million.

DHA served as the prime consultant on this federally and locally funded project in Tracy.

DHA’s services included:

  • Project Management
  • Agency Coordination
  • Bridge Design
  • Civil/Roadway Design
  • Utility Coordination
  • Construction Support
  • Environmental Monitoring

The project was a model of collaboration from the beginning through construction completion. Much of this project’s success can be attributed to diligent proactiveness by the DHA design team, the Hanna Group CM team, Teichert and MCM prime contractors, and the City of Tracy.

City of Goleta wins Bikeways and Trail Project of the Year

Drake Haglan and Associates (DHA) is proud to congratulate the City of Goleta on the Bikeways and Trail Project of the Year Award for the Hollister Avenue Class I Bike Path/Multi-Purpose Path SRTS Project.  Awarded by the American Society of Civil Engineers (ASCE) Los Angeles Section, the project is recognized for its unique technical achievements, its complexity, scope and engineering features.

The project included curb extension intersection treatment, Class II bike lane, Class I bike path, sidewalk, bus pullouts, lighting and traffic signal, bioretention, and landscape and irrigation improvements.  Additionally, the project included reconstruction of one mile of roadway with crown correction, hardscaped and landscaped medians on Hollister Avenue between Ellwood Elementary School and Pacific Oaks Road. The path promotes active and sustainable transportation for all. 

DHA is proud to have prepared design and construction bid documents, and provided construction support for the project.

Job well done City of Goleta! 

Congratulations!

Congratulations to the City of Goleta on their Project of the Year Award

Drake Haglan and Associates is proud to congratulate the City of Goleta on the Hollister Avenue Class I Bike/Multi-Purpose Path Project of the Year Award in Santa Barbara County issued by the Santa Barbara-Ventura Branch of American Society of Civil Engineers (ASCE). The 14-foot wide concrete path along Hollister Avenue from Ellwood Elementary School to Pacific Oaks Road makes travel to and from the school more accessible for students living in the area, and also serves UCSB students, recreational riders and commuters. The path promotes active and sustainable transportation for all. Sharing in the City’s success, Drake Haglan and Associates prepared design and construction bid documents, and provided construction support for the project.

50 Corridor TMA Engineering Roundtable

Drake Haglan and Associates is proud to join the City of Rancho Cordova in sponsoring the 50 Corridor TMA’s Engineering Roundtable on March 15th. The goal of the TMA is to improve the quality of life through effective transportation planning. This public-private partnership promotes alternative transportation for those who live and work on the 50 Corridor.

This month’s speaker will be Sal Akhter from Streetlight Data, Streetlight Data creates analytics that shine light on mobility behavior. They use cell phone data to aid urban planning, transportation infrastructure design and project evaluation. They use “Big Data” to understand travel patterns, and focus on reducing VMT and improving transportation access and equity.

The TMA improves mobility along the 50 corridor through Advocacy, Employer Support, and Employee support. More information about the TMA is available at: www.50corridor.com

Alhambra Valley Road at Pinole Creek Washout Repair | Contra Costa County

DHA, through an on-call agreement, provided emergency design services for a washout and culvert replacement for Contra Costa County at Alhambra Valley Road over Pinole Creek.  Due to an existing debris blocked culvert pipe, creek flows overtopped the culvert and eroded away the existing 2-lane Alhambra Valley Road to a depth of approximately 25-feet below the road surface.
