Three Rivers Convention Center is a multi-purpose convention and meeting facility located at 7016 W Grandridge Blvd in Kennewick, Washington. Opened in 2004, it is owned by the Tri-Cities Public Facilities District and managed by VenuWorks, the same company that operates the adjacent Toyota Center. The venue offers approximately 75,000 square feet of flexible event space, with capacity varying by setup and the Great Hall accommodating several thousand guests for banquets, expos, and seated events.
The convention center is regarded as the premier convention and large-gathering facility in the Tri-Cities region of southeastern Washington, drawing events from across the Columbia Basin. Its event mix includes conventions, trade shows, expos, corporate meetings, conferences, banquets, community galas, seasonal events, concerts, comedy, and performances presented in seated or ballroom configurations.
A major expansion with a guaranteed maximum cost of $71.3 million is scheduled to open December 4, 2026, significantly enlarging the facility’s exhibition and meeting footprint. Three Rivers Convention Center is known for its large divisible halls, meeting rooms, pre-function spaces, and its role as a flexible event hub within the Columbia Center district.
Three Rivers Convention Center is located at 7016 W Grandridge Blvd, Kennewick, WA 99336 — in the Columbia Center commercial and hospitality district near surrounding retail, dining, hotels, and the adjacent Toyota Center.
Driving and Parking: The area is car-oriented, and driving is the primary option for many attendees. The venue is easily accessible from Interstate 82 and U.S. 395, with ample on-site and adjacent surface parking shared with the surrounding Columbia Center retail district. Parking is generally free, though large public events can draw heavier traffic and fill nearby lots faster.
Transit: Three Rivers Convention Center is served by Ben Franklin Transit, the regional bus system for the Tri-Cities. Transit is available, but it is secondary for most attendees because the surrounding Columbia Center area is built around vehicle access.
Rideshare: Uber and Lyft operate in the Tri-Cities, and rideshare drop-off and pickup are straightforward thanks to surface-level entrances and ample curb space. After larger events, building in extra time for pickup can make departure smoother.
Nearby Accommodation: Numerous hotels cluster in the Columbia Center and Grandridge Boulevard area immediately around the venue. Staying nearby can make it easy to walk or take a short drive to the convention center, especially for multi-day conferences, expos, and banquet events.
Three Rivers Convention Center has a practical, single-level layout built around lobby and pre-function areas that lead into the Great Hall, additional meeting rooms, and flexible event spaces. Because seating, tables, registration areas, and expo layouts change by event, reading signage and giving yourself a few extra minutes on arrival helps you move efficiently.
Entrances and Access: Ground-level main entrances open into lobby and pre-function areas, with access continuing into the halls and meeting rooms. The surface-level setup keeps arrival simple for conventions, galas, performances, and public expos.
Concourse Levels: The convention center is primarily a single-floor facility. Its layout centers on a large divisible main hall known as the Great Hall, supported by meeting rooms and lobby spaces that can be arranged differently from event to event.
Accessibility: As a modern facility, Three Rivers Convention Center provides ADA-accessible entrances, restrooms, and parking. The single-level design also supports easier mobility throughout the building.
Getting to Your Section: Open hall layouts use event-specific signage and staff direction. Seating arrangements, table assignments, registration desks, booths, and stage placement vary by setup, so following posted signs when you arrive is the best way to reach the right area quickly.
Three Rivers Convention Center offers on-site catering and concessions for events. Alcohol service is available for applicable functions, and the dining experience can vary depending on whether you are attending a banquet, gala, conference, expo, or seated performance.
The convention center is located within the Columbia Center retail and dining district, with numerous chain and local restaurants along Grandridge Boulevard and near the Columbia Center mall. Attendees can find dining options within a short walk or drive, making the area convenient for pre-event meals, conference breaks, and post-event gatherings.
Three Rivers Convention Center maintains security and venue policies that are updated regularly and may vary by event. Before attending, reviewing the current policy on the venue's official website is strongly recommended.
Bag Policy: Bag policies vary by event and promoter. Bag checks may apply for larger public events, so bringing only what you need can help entry move faster.
Commonly Prohibited Items: Outside food and drink, weapons, and other items restricted under individual event rules are typically prohibited. Event organizers may also apply additional restrictions based on the type of gathering.
Re-Entry: Re-entry rules vary by event and are shown on the event listing. For some conventions and multi-session events, badge or registration procedures may also guide access throughout the day.
Entry Procedures: Entry can include ticket or registration verification, with screening expectations depending on the event. Arriving with tickets or registration materials ready can help keep the line moving.
Three Rivers Convention Center is part of the broader Tri-Cities live-events market, with Kennewick, Pasco, and Richland offering arenas, expo facilities, parks, theaters, and smaller performance spaces.

Three Rivers Convention Center ticket prices vary significantly depending on the type of event, the performer or program, seating section, and demand — which is what you'd expect from a venue that hosts everything from community expos and seasonal events to galas, banquets, and ticketed performances.
Community events, seasonal gatherings, and expos can often range from free admission to low-cost or modest admission, depending on the organizer, program, and whether the event includes special activities, displays, or premium access.
Banquets, galas, and ticketed performances typically fall into a mid-range pricing pattern, with cost shaped by the event format, entertainment, table or reserved seating arrangements, and the overall demand for the program.
For popular seasonal and ticketed events, buying earlier generally secures better availability. As inventory shrinks and the event date approaches, the best remaining seats, tables, or admission options can become harder to find.
