Yes, the road is there. It is quite straightforward: the on-ramp to I-5 is right next to the prison itself, then it's a straight road to the SeaTac from the off-ramp.
As the Johnson mentioned, there would be:
- Two Lone Star officers in the Black Mariah itself, both in the driver's compartment. One is a dedicated rigger, another is a guard - a defensive system operator - who is jumped into the defensive system;
- Four Lone Star officers in a Lone Star patrol car. All of them are your regular cannonfodder - not a SWAT team or anything. Although it is noted that they will have better armament;
- Four PCC military officers in a Lone Star patrol car. They are underequiped by military standards, more up to the SWAT level. One of them is a shaman, but there is no detailed information on him, not even a name.
The vehicles are:
- Lone Star "Black Mariah" Ultra-Security Prisoner Transport Vehicle (USPTV). Ultra indeed: the prisoner compartment and the driver's compartment are separate, both extensively armored. Both compartments are also environmentally sealed. Slightly lighter armor encloses the engine compartment. Ballistic shrouds protect the two front wheels and the quads in the rear. The tires are runflat. There are two turrets on the sides of the prisoner compartment and the whole vehicle is lined with directional anti-personnel explosives and "stun" explosives approximately on waist level. Moreover, the prisoner compartment itself is rigged with explosives: if the compartment is forced open or a signal comes from the defensive system operator - the prisoner is gone. A Dead Man's Switch triggers the explosive charge in case the defensive system operator is jacked-out without issuing a disarming command. Flash-packs are incorporated into the light bar on top. There is also a gas delivery system in place, usually loaded with Neuro-stun. The car is built on a standard Chrysler-Nissan one-ton truck chassis;
- Patrol cars are your regular (well, not by Seattle standards nowadays, but still) Chrysler-Nissan Journeys.
As the convoy leaves at night only light traffic is expected.
