Sixth Street Viaduct Will Increase
Pedestrian and Cyclist Connectivity
For decades, the Sixth Street Viaduct has served as a critical transportation link between the Los Angeles neighborhoods of Arts District and Boyle Heights. However, the sidewalks were dangerously narrow and bike lanes, non-existent. The new viaduct has been designed to not just alter those shortcomings but to create new, safe ways for pedestrians and cyclists to cross the viaduct and reach the planned park below. 
Pedestrian Access
There will be multiple points of entry for pedestrian access, including five sets of stairs from the deck to the ground below. This includes one on the west side of Santa Fe Avenue and four on the eastside between Mission Road and Anderson Road.
The walkways on each side of the bridge vary from 8 feet to 14 feet in width and will be illuminated with LED lighting. These walkways will also be separated from bicycle and traffic lanes by concrete barriers which run the entire length of the bridge.
Bicycle Safety
The viaduct will serve as a more convenient way for recreational and transit-dependent riders to get to and from their destination. The protected bike lanes will be 10 feet wide and separated from vehicle lanes by bollards and curbs that run the length of the viaduct. Cyclists will be able to travel east from the Mateo Street viaduct entrance into Boyle Heights, as well as travel west from the Boyle Heights viaduct entrance and ride into Downtown LA. These bike lanes will expand LA County’s bicycle network, helping the city become even more cyclist friendly. In addition, the helical ramp will provide access to cyclists from the viaduct to ground level.
The Helical Ramp: Designing Efficiency, Creating Connectivity
The ADA-compliant helical ramp structure, which is located near the center of the viaduct, will have a connection to both the westbound and eastbound bicycle lanes and sidewalks at the deck level. Using the ramp structure, pedestrians and cyclists will be able to connect from the ground level at Mission Road into the communities of Boyle Heights and the Arts District. 
The helical ramp will also help connect the viaduct to the future 12-acre PARC under the viaduct, which will be located at ground level and include recreation and open spaces, connections to the LA River and more. The PARC will also include the Len Hill Arts Plaza, made possible by the generous support of the Leonard Hill family. 
We envision the viaduct as a bridge that will not only provide multimodal opportunities between Boyle Heights and the Arts District, but will also connect people throughout the greater Los Angeles community.
