Designs for a new pedestrian and bicycling bridge spanning Interstate 84 in Portland are starting to take shape.

Portland's Design Commission will discuss the latest designs at its June 7 meeting, the second briefing this year on the car-free bridge.

The Sullivan's Crossing, an estimated $13.5 million bridge connecting the Lloyd and Central Eastside Industrial Districts, will span the freeway and connect to Northeast 7th Avenue on both sides.

Construction could begin July 2019 and last until December 2020, according to city records.

The close-in neighborhoods are separated by the freeway, and pedestrian and bike access are limited. The new span will be capable of handling emergency vehicles if necessary.

According to city documents, the basic structure and form of the Sullivan’s Crossing have already been determined. The Design Commission will give feedback and advice on the color of the bridge and lighting as well as “urban design elements at the north landing.”

Renderings depict a 470-foot-long span with a slight arch and high railings.

Transportation development fees charged to new construction projects are the primary source of funding. Go Lloyd, a nonprofit public-private partnership group that advocates for transportation and economic development issues in the neighborhood, will also contribute to the tab.

The design commission meeting is at 1:30 p.m. Thursday, June 7, at 1900 S.W. 4th Ave., Room 2500B.

City transportation leaders are also holding a public open house June 18 from 4 to 6 p.m. at Metro regional government’s offices at 600 N.E. Grand Ave.

A second, long-awaited pedestrian and bicycle bridge is also slated to begin construction next year. The Flanders Crossing, which would span Interstate 405 and connect the Pearl District and Northwest neighborhoods, is projected to cost $6.4 million.
