Music lovers in southwestern Connecticut will have to wait a bit longer than expected to see their first show at a planned new outdoor amphitheater.

After breaking ground two months later than expected, plans to renovate and reopen the former Bridgeport Bluefish baseball stadium as a boutique concert venue are moving ahead, but at on a delayed schedule.

Developers are looking at roughly 15 months of a construction before performers can hit the stage — and that’s barring another harsh winter.

“We’re looking at opening summer or late summer (2019),” said Howard Saffan, principal of the Harbor Yard amphitheater. “If Mother Nature kills us in the wintertime, then maybe it will go beyond that.”

Plans originally called for the facility to open next spring.

Saffan said past tensions between the city and the neighboring Webster Bank Arena, which is owned by the city and operated by parent of the Sound Tigers hockey team, have played a factor in the delay.

The issues date to 2015 when the Ganim administration came back into office and said the Sound Tigers owed back rent to the city. The two sides have butted heads on several occasions since then, including when the amphitheater was first proposed. The arena hosts some musical acts when the hockey team is out of town.

In the past the Sound Tigers have said that if the amphitheater goes through then the team would consider leaving town, but Mayor Joe Ganim said that has not come to fruition.

Ganim wouldn’t specify as to whether tensions with the arena delayed the groundbreaking, but developers and officials said they have come to an accord that would benefit both parties, which Saffan has been touting since the projected was announced.

“It sounds like they’ve got something worked out, to the extent that they can help the arena,” Ganim said. “The arena is a big part of downtown, it’s a big part of the city and so is this kind of exciting to have them side by side like this.”

Saffan said the arena would be allowed to use the amphitheater’s dressing room and star rooms to entice acts.

“It’s no secret that there have been some issues with the arena and the city, and I think they’ve finally come to some sort of agreement and that’s what was delaying it,” Saffan said.

Jim Koplik, president of Live Nation Connecticut and Upstate New York, which is working with the venue to book concerts, has been touted as a partner in the amphitheater project.

Along with bringing in performers to the new venue, Koplik said he and his team have also served as consultants during the designing process.

Koplik said he has been considering future acts for the venue but delays and an unclear opening date haven’t made it easy for the promoter to lock in artists for what would be a limited 2019 schedule.

“We don’t even know when we’re opening yet,” he said “We’d like to open this time next year but if it’s a tough winter we might not be, so it’s hard to pin anybody down, so we just talk in general.”
