Nebraska plans to execute the state's and one of the country's longest serving death row inmates.

Carey Dean Moore was sentenced to death nearly 40 years ago for the shooting deaths of Reuel Van Ness, Jr. and Maynaqrd Helgeland in Omaha.

Correction officials said Moore's execution will be carried out by lethal injection at 10 a.m. on Tuesday, August 14 at the Nebraska State Penitentiary.

Here are some things to keep in mind if you are planning on attending the execution.

Large crowds of protestors on both sides are expected to attend. Members of the public will be allowed on the grounds at 8 a.m. Protestors can be dropped off near the Amigos/Kings.

Police officers will be staffed to help pedestrians cross at south 14th, Pioneers and south 8th and Pioneers and Highway 2. Entry to the State Pen grounds will only be allowed at south 14th.

Once you get onto the State Pen grounds, you must identify as a proponent or opponent. You will then be directed to the appropriate area. You are also subject to search.

As a reminder, no backpacks, coolers or chairs are allowed on the ground. Only hand held signs are allowed. You cannot bring in signs mounted on poles or sticks. Also, you must leave the prison ground no later than one hour after the completion of the execution.

Now when it comes to death penalty opponents, they say they have gathered more than 60,000 signatures calling on Governor Pete Rickets to stop the state from carrying out Tuesday's execution.

Organizers submitted the petition to Ricketts' Monday.

The ACLU of Nebraska is also asking the State Supreme Court to delay the execution.

The ACLU said it should be delayed until the state's highest court hears arguments in a separate case focused on the legislature's 2015 vote to abolish capital punishment.
