The Greater Pittsburgh Food Bank will hold a drive-up food distribution from 11 a.m. to 1 p.m. Tuesday at the Big Butler Fairgrounds in Prospect.

Reservations are required, as no more than 550 cars will be served. Each vehicle will receive a 50-pound box of food.

Those receiving food must be in the vehicle named in the online reservation. Each household using the vehicle must fill out a separate reservation. One vehicle can be used for a maximum of three households.

Vehicles must be in park with the trunk or back seat unlocked when recipients pull up to receive their food. The box will be loaded into the vehicle by a worker at the distribution site.

To make a reservation, log onto pittsburghfoodbank.org and click on “Get help.” A link for drive-up food distribution events will appear with a list of upcoming distributions.
