Broadway Pop-Up Demonstrations

Caltrans and our partners have many plans and ideas to improve Broadway in Eureka, and we will test some of those ideas soon.

Caltrans District 1 will be holding pop-up demonstrations along the Broadway portion of U.S. 101 in Eureka. These test demonstrations will 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.

Both the Broadway Pop-Up Demonstrations and permanent improvements are being planned and designed in close coordination with our partners, including the City of Eureka, Humboldt Transit Authority, Humboldt Bay Fire, Humboldt County Association of Governments, and with the input of numerous community-based organizations.

The Broadway Pop-Up Demonstrations are tentatively planned for May 2023.

Temporary Pop-Up Demonstrations Map (Details subject to change)

Broadway Pop-Up Demonstrations will include the following features:

  • A 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.

  • Temporary curb extensions between Papa & Barkley and 6th 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.

  • The 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.

  • The relocation of the southbound bus stop from McCullens Avenue to the southern Bayshore Mall entrance in front of McDonald’s. This will give transit riders and bus operators an opportunity to provide feedback on how well the new stop location works for them. Signage will be placed to alert riders of the temporary location, and riders will still be able to board or arrive at McCullens if necessary.

  • 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.

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.

Broadway Pop-Up Demonstrations Virtual Public Meeting | June 28, 2022

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.

A roadway intersects with another. At the right turn, temporary bollards are installed to simulate a wider curb area.
