David Byrne might have asked "where does that highway go to;" however, he did not ask where the signs on the highway originated.  The PennDOT Sign Shop, located behind the District 8-0 headquarters in Harrisburg is where signs for installation along the state maintained highways are produced.  They make signs for not only PennDOT, but also the Pennsylvania Turnpike Commission.  Local municipalities can also purchase signs for use along their streets from the shop.

	The main Sign Shop building where most of the fabrication takes place. (Jeff Kitsko)
	Shelves full of 3M Diamond Grade Reflective Sheeting.  The material which is used on signs, reflects headlights at night for better visibility.  (Jeff Kitsko)
	Sign in the process of fabrication.  The sheet of metal is slid into the machine, where a roller applies the 3M sheeting onto it, in this case yellow as can be seen spooled above.  (Jeff Kitsko)
	Lettering being applied to a destination sign to be used near Johnstown in District 9-0.  (Jeff Kitsko)
	Sheet of lettering being applied onto a Safety Corridor sign.  The letters are first laid out on a piece of wax paper to align them properly, then using small rollers, are applied to the sign itself.  (Jeff Kitsko)
	Another side of the sign shop, not in use this day.  The overlays used to be applied by straight edges made of pine; however, they would absorb humidity and end result in warping. (Jeff Kitsko)
	Blanks route shields of all sizes and all types, sitting and awaiting numbers. (Jeff Kitsko)
	Warehouse which stores the finished products.  Whatever type of sign is needed, it can be found here.  (Jeff Kitsko)
	Plotter that automatically cuts out letters from a sheet of 3M material, numbers, other characters, etc with exact precision to be applied to signs.  The objects to be cut out are in a computer that is connected to the plotter.  (Jeff Kitsko)
	An older plotter in the same room that does the same job, just a little slower.  Before the use of computers, employees would have to cut out the characters by hand as best they could.  (Jeff Kitsko)
	Map showing the routes between the Sign Shop and the district offices.  The ones closer to Harrisburg such as 5-0 and 6-0 send trucks for signs more often than ones such as 1-0 and 2-0.  (Jeff Kitsko)
