Bulky deliveries should be made to the loading dock, which is on the south side of the Department of Transportation building, accessed from the west off of Walnut Avenue through what is noted on the map as the O.D.O.T. Garage area.

Loading dock building entrances are electronically locked. If you are making a bulky delivery for Materials and there is not an employee on the loading dock to assist you, please use the telephone on the dock to call Materials. Their number is listed on a sign by that telephone and is 521-2677.

All other visitors should enter through the main Department of Transportation building entrance on the north side of the Department of Transportation building and check in with building security.
