The Sullivan Arena operated on and off as a homeless shelter since the pandemic began in 2020. In May 2023, the homeless shelter shut down, as Anchorage mayor Dave Bronson said it needed to return to hosting hockey games and concerts. When the homeless shelter at Sullivan shut down, homeless camps in Anchorage's parks and green areas exploded in size. Anchorage officials have no plans to provide another winter shelter. [9] On July 9, 2024, the Wolverines confirmed that they would relocate from Ben Boeke Ice Arena to Sullivan Arena for the 2024-25 season.
For hockey, the Sullivan Arena offers 6,251 seats with a standing room capacity of 6,451. If areas designated for wheel chairs are included, the arena can seat 6,290, plus standing room, during hockey games. The arena is noted for having an international-dimension (Olympic-sized) ice rink (61 m × 30 m / 200 ft × 98.5 ft) instead of the NHL dimensions (200 ft × 85 ft / 61 m × 25.9 m) common among North American venues. The main arena floor contains 32,000 square feet of space.
In 2014, a new center-hung scoreboard, with four 8-by-8-foot video screens and a wraparound LED display system was installed to replace the 80s-style scoreboard which had a black-and-white dot matrix display. The new scoreboard was previously installed at the Cow Palace in Daly City, California, where it was used by the ECHL affiliate of the San Jose Sharks, the San Francisco Bulls. The Bulls purchased the scoreboard for their first season in 2012 but the team folded less than two years later. The scoreboard is made by Colosseo, a European company specializing in stadium and arena LED and entertainment technology.[10]
There were plans, projected for 2015, for the neighboring Mulcahy Stadium to be demolished and rebuilt to its west in order to create 400 new parking spaces for the arena.[11] In addition, all seats and telescopic risers inside Sullivan Arena were replaced, the arena floor was rebuilt, and its ice-making equipment was upgraded for the 2015–16 hockey season. Another renovation in 2017 expanded the arena's storage space by 5,000 square feet, replaced the arena's portable stage, floor seating and artificial turf, and improved the arena's acoustics.
