The Cavaliers’ 8 p.m. game against the Minnesota Timberwolves Wednesday will mark the first event impacted by changes stemming from the transformation of Quicken Loans Arena.

For the next 18 months, traffic on Huron Road between Ontario Street and East Ninth Street will become one way eastbound before events and one-way westbound afterward. It is expected that will take place two hours before Cavs’ tipoff and 90 minutes before the start of Lake Erie Monsters games, which are also the new times for the arena gates’ opening.

During non-event times, traffic will be reduced to one lane in each direction on Huron Road.

For the rest of the Cavs season, parking in the Gateway East Garage will be limited to those with passes or pre-paid tickets, which are sold out. Fans are encouraged to carpool or use RTA or Uber, and also to arrive early. For additional parking options, go to TheQTransformation.com. New Uber users can use the promo code CAVS2018 and receive up to $15 off their first ride.

A Cavs spokesperson said it may take a few games for the team and the Cleveland Police Department to come up with an efficient system.

Barricades have gone up marking construction zones, which will eliminate access to some sidewalks. Crosswalks on the Huron Road side of the Q will be redefined. Guest services representatives will be stationed outside the arena to help fans through the changes.

The JACK Casino north bridge connector to the Q will remain open for the rest of the Cavs season before being eliminated this summer. The Gateway East Bridge and the JACK north bridge will be accessible for guests in wheelchairs. The curbside drop-off for those in wheelchairs will be at the RTA Walkway entrance on Ontario Street.

The RTA walkway from the Tower City food court to the Q will open four hours prior to Cavs’ games and remain open for three hours afterward. For other events, the times will be three hours and approximately three hours, respectively.

The modernization of the 23-year-old arena is expected to take about 20 months. There will be no events held during the summers of 2018 and 2019.

“While construction will require that we undergo some temporary inconveniences along the way, we thank everyone for their patience as we ask them to ‘pardon our dust,’” Len Komoroski, Cavaliers and Quicken Loans Arena CEO, said in a statement. “With a project of this magnitude, we will continually monitor and adapt as necessary to provide the best experience possible for everyone as we build a better Q for tomorrow.”
