Broadway in Austin's 2018-2019 season opens Oct. 23 with "The Play That Goes Wrong," and promoters have announced new security procedures for the shows at Bass Concert Hall.

People who have been to a Longhorns football game or concert at the Erwin Center recently will know these already — Bass is adopting the same safety and security policies, which includes metal detectors at entrances.

Want to speed up your entry? Go bag free and take the express lane at the far-right entrance. Plan for more time for getting in as staff and patrons get used to the changes.

The Broadway in Austin season includes the much-anticipated Austin premiere of "Hamilton" in the spring.

Here are the new entrance policies, which officially start Oct. 22:

• Bags must be clear and the size must not exceed 12" x 12" x 6". Small non-clear clutch bags that do not exceed 6.5" x 4.5" will be permitted. One-gallon size clear re-sealable plastic storage bags are also acceptable.

• Walk-through metal detectors are being added at the Bass Concert Hall entrance. In order to increase the efficiency of this process, guests should minimize the number of personal items they bring and remove any items that may trigger the alarm before walking through the detectors. If an alarm sounds, the guest will be subject to a secondary screening. Guests without bags may enter through an express lane located at the far-right entrance.

Prohibited bags include:

Purses

Diaper bags (put items usually carried in a diaper bag in a clear plastic bag)

Cases (camera, binocular, etc.)

Backpacks

Fanny packs

Printed pattern plastic bags

Reusable grocery totes

Mesh or straw bags

Duffel bags

Large totes
