[2] At the intersection, located near Gonzaga University, SR 290 turns east and becomes Trent Avenue before crossing the Spokane River again.

[5] Trent Avenue travels northeast through an industrial district, paralleling the Spokane International branch of the Union Pacific Railroad,[4][6] through Millwood before intersecting SR 27, locally named Pines Road.

[2] The state legislature established a spur route of SR 290 in 1977 to connect it with I-90, using a recently built interchange at Liberty Park that was intended for the cancelled north–south freeway project.

[2][17] The spur would require a new crossing of the Spokane River, named the James E. Keefe Bridge, and funding for its construction was delayed several times due to other needs in the state.

[18] The bridge's construction was plagued with issues, including a survey error that resulted in several misplaced piers, and an audit was conducted by the state after it was completed in November 1984.

[22][23] The new bridge at the location, which incorporated similar design features but also includes bicycle lanes and wider walkways, opened to traffic in July 2023.

This spur route followed a portion of the cancelled North/South Freeway, which was intended to bypass Downtown Spokane and the Division Street corridor.
