Colorado Street BridgeTimeline

Agreeing to a barrier was only the first step

Follow the project from emergency fencing to questions about what permanent barrier to build and how to pay for it.

Before the barrier project

The Colorado Street Bridge opened on December 13, 1913, giving travelers a crossing above the Arroyo Seco instead of the steep descent required to reach the earlier Scoville Bridge. Its curved alignment helped the builders find firmer ground for the foundations. It later carried Route 66 and reopened after restoration in 1993.

That history helps explain the importance of preserving the bridge’s character as Pasadena considers permanent protection.

Who decides what?

The City’s project records distinguish four roles:

Public Works and the design team
City staff and hired architects and engineers develop and refine the designs, drawing on technical advice and public input.
Historic Preservation Commission and Design Commission
Review the proposed designs and advise the committee and Council.
Public Safety Committee
Reviews the work, gives staff direction, and makes a recommendation to the City Council.
City Council
Decides whether to approve a barrier concept and the next steps.

After concept approval, the City still has to complete detailed design, environmental documents, and construction documents. Building the barrier also requires construction funding and contract authorization.

The records reviewed for this guide describe continuing design work and further review, with no confirmed date for the next Bridge decision.

Physical changes and project decisions, side by side. The complete chronology remains below.

Jul 2017

Emergency fencing around the seating areas

On the bridge

Temporary fencing was placed around the seating alcoves.

Project decisions and work

Pasadena fenced the restored seating alcoves, the recessed areas with benches. A task force with members from several fields then studied longer-term protection.

May 2019

The first design contract was approved

The Council approved the Donald MacDonald Architects contract after a revised proposal shortened the design schedule by ten months and reduced the proposed contract from $700,000 to $500,000. The forecast placed Council concept approval in December 2019 and construction in August 2020, if the City approved the funding. These were estimated dates. Funding for construction had not been approved.

Feb 2020

Design alternatives and a March–May forecast

The February 2020 presentation compared straight mesh, pickets, curved mesh, and a hybrid. It projected mockup installation in March, commission reviews in April, and a committee recommendation and Council approval in May. At the meeting, Kennedy requested a cost estimate for enclosing the bridge with a roof before Council consideration.

The February 3, 2020 presentation separates the task force’s recommended minimum height from the consultant’s broader design criteria. Those criteria included height, resistance to climbing, historic preservation, appearance, and emergency access. Slides 10–27 show the design options and their different dimensions.

Slide 30 ranks curved mesh highest among the options shown, but it does not identify the final mesh type.

Slide 31 gives the projected schedule for March through May. Kennedy’s request for a roof over the barrier appears in the meeting minutes on page 2, not in the presentation. Page 3 says the committee received and filed the information; it does not say the committee approved a permanent design.

2022–2023

The design process restarted with another consultant

The September 2022 report scheduled a Public Safety Committee return for September 2023. The first request for proposals received no proposals. A February 2023 newsletter forecast a return by year-end. The City invited proposals again and awarded the Apexx Architecture contract on April 14, 2023.

Jan–Jul 2024

Review narrowed the options without a final selection

The Design Commission reached no consensus in January. By July, staff’s options had narrowed to vertical webmesh and metal pickets, and staff returned with patrol costs, netting analysis, rescue concerns, and survey results.

Planned dates and what happened next

These dates were estimates. Finishing the design is one step. Building the barrier is another.
