Broadway Pop-Up Demonstrations

A map defines the scope of the Broadway Pop-Up Demonstrations from south of Eureka at Papa & Barkley's north to 6th Street. The map shows cross streets of Harris and Wabash.What is a pop-up demonstration, you ask? 

A pop-up demonstration is a temporary installation to test roadway enhancements and get input to inform future permanent projects. 

Watch the following video or read further for more information.

Caltrans District 1 is holding pop-up demonstrations along the Broadway portion of U.S. 101 in Eureka. These test demonstrations include the temporary installation of materials like vertical cone-like delineators and paint to analyze proposed improvements before possible construction.

The projects are intended to enhance safety for all road users, improve connections to local roads, improve transit access for pedestrians and cyclists, and make walking and bicycling a more enjoyable experience on Broadway. The Broadway Pop-Up Demonstrations will allow Caltrans to understand potential impacts of these improvements on all road users, receive feedback from stakeholders and community members, and make adjustments to project designs before permanent construction.

The Broadway Pop-Up Demonstrations were in place in May and June 2023.

Broadway Pop-Up Demonstrations will include the following features:

Temporary Class IV bikeway between Hawthorne and Wabash

Class IV bikeways have a vertical element between the vehicle lane and the bike lane. This design is intended to make bicyclists more visible and comfortable and potentially reduce collisions.

Delineators mark temporary bike lanes on northbound Broadway in Eureka, California.

Temporary curb extensions between Papa & Barkley and Sixth Street

Curb extensions—also known as bulbouts—are extensions of the sidewalk into the parking lane or shoulder at intersections. They help make pedestrians waiting to cross the street more visible to drivers. They also slow vehicles making turns. The demonstrations will not be adjusting any curbs or sidewalks. Delineators or posts will be placed where curbs may be constructed in the future. Curb extensions are not intended to prohibit any turning movements, and drivers will be able to make their regular turns at locations with temporary curb extensions during the demonstration period. Pedestrians should still stop at the curb and wait until it is safe to cross before stepping into the test curb extension area.

Closing of acceleration and deceleration lanes at Papa & Barkley and the southern Bayshore Mall intersections

Acceleration lanes provide space for turning drivers to speed up before merging into traffic, and deceleration lanes provide space for drivers to slow down without slowing through-traffic before making turns. The test locations are signalized, which stops cross traffic and allows drivers to make turns onto Broadway without needing to merge into traffic. In the proposed permanent project, the spaces used for acceleration and deceleration lanes will be reallocated to transit stops, bicycle facilities, and/or pedestrian use. The demonstration will temporarily use delineators to close or modify these acceleration and deceleration lanes.

Delineators mark a temporary closure of the deceleration lane at the southern entrance to the Bayshore Mall on Broadway in Eureka.

Closing the median near Papa & Barkley, near Hilfiker Lane and near KFC

The demonstrations will temporarily use delineators to close the median at locations of proposed pedestrian crossings or traffic calming islands to understand impacts to drivers including emergency responders. The demonstrations WILL NOT include any marked crosswalks, pedestrian refuges, or other pedestrian crossing enhancements. Pedestrians should not use these locations to cross Broadway.

Delineators mark temporary closure of a median in south Eureka, California to evaluate a potential median refuge in this area.

These features are being evaluated in a temporary condition to inform project designs and implement the vision laid out in the Broadway Multimodal Corridor Plan.

Thank you to our partners who have been involved in the planning and design of improvements on Broadway:

  • City of Eureka
  • Humboldt County Association of Governments
  • Humboldt Transit Authority
