The first part of the Civic Arena roof is being demolished today. From the Trib:
Demolition crews are planning to drop the first of eight roof panels over the Hill District arena at 10 a.m. this morning. The first panel to fall will be one of two on the city side of the building, making the demolition visible to people on the arena's west or Downtown side.
To open up the roof, contractors plan to cut the structural supports below so that the panel falls onto the arena floor where it will be cut into small pieces for removal. The work for each roof panel will take about a week to two weeks to complete.
The final step of removing the roof will be cutting up the cantilever arm that has held the entire piece in place for the past 50 years.
You may or may not be able to see something on the repurposed Consol construction cam/Igloo destruction cam.
