11th Street East Tracy Overhead Bridge Replacement Project Awarded Project of the Year

Drake Haglan and Associates is proud to congratulate the City of Tracy on receiving the Transportation - Bridge Category $10 - $50 Million Division Project of the Year for the 11th Street East Tracy Overhead Bridge Replacement Project.  The award was issued by the American Public Works Association (APWA) Sacramento Chapter for the single-span structure with an overall bridge length of approximately 291-feet and roadway approach work of 3,400-feet supported by MSE walls to minimize the amount of right of way required and improve site aesthetics.

The existing bridge was a 1,441-foot long, 64-foot wide, multiple simple-span bridge consisting of reinforced concrete T-beams and steel girders, and crossed over three separate Union Pacific Railroad (UPRR) tracks at a skewed angle.

DHA designed a shorter highly-skewed structure in combination with retaining walls and embankment fill at the approaches to span the UPRR mainline tracks.  The superstructure of the replacement bridge consists of a cast-in-place, post-tensioned concrete box girder.

The City’s goal of improved pedestrian safety was also met on this project.  The new roadway section consists of two 12-foot wide through traffic lanes in each direction, 4-foot wide median, 8-foot wide shoulders which serve as Class II bicycle lanes, and 8-foot wide separated mixed use paths on each side that are protected with traffic side barriers.

Much of this project’s success can be attributed to diligent proactiveness by the DHA design team, the Hanna Group CM team, the prime contractor(s) – Teichert/MCM, and the City of Tracy – managed by Zabih Zaca.

The project was a model of collaboration from the beginning through construction completion.

Job well done City of Tracy!  Congratulations!


Christa Redd joins DHA’s Environmental Group

Please welcome, Christa Redd, who recently joined Drake Haglan & Associates (DHA) as a Senior Environmental Project Manager.  With 20 years’ experience providing CEQA and NEPA compliance throughout California, Christa has expertise working in Caltrans Districts 1, 3, 4, 5, 6, 7, 8, 10, 11, and 12 and will provide DHA clients experience, knowledge, and ability to effectively navigate through the Caltrans environmental process.  She has consistently worked on both Local Assistance and Caltrans-lead projects. 

Christa’s college career led her to Oregon State University where she received a BS in Environmental Science, UC Davis Extension where she earned a Certificate in Land Use and Environmental Planning, and University of Nevada, Reno where she earned a MS in Environmental and Natural Resource Sciences.

Throughout her career, Christa provided project analysis and management for a variety of CEQA and/or NEPA projects including transportation (roadways and bridges) to residential, commercial, industrial, institutional, alternative energy, and forest and watershed restoration projects.  She has recently been involved with development application and land use regulation projects related to California’s commercial cannabis industry.  Christa has worked on projects throughout California, as well as portions of Nevada and Arizona. 

While camping, salsa dancing, and fly-fishing are her passions, Christa doesn’t get to do them very often.  These days she can be found on the sidelines cheering on her boys’ soccer, basketball, and baseball teams, or shuttling them to scouting activities or music lessons.  She has also learned to fully embrace college football season, having married into an LSU family.

We are excited to have Christa join the DHA team and look forward to her leadership with the continued growth of the DHA Environmental Group.

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.
