Context paragraphs:
Pennsylvania Route 283: Pennsylvania Route 283 (PA Route 283 or PA 283, officially State Route 300 or SR 300 due to the presence of Interstate 283) is a 29 mi state highway in the U.S. state of Pennsylvania.  It connects Harrisburg to Lancaster as a freeway, paralleling the old U.S. Route 230 (now partly Pennsylvania Route 230).  The number was assigned based on the proximity of Interstate 283, but Interstate 283 and PA 283 are not the same roadway; the two intersect at a cloverleaf interchange.  Because the road is built to Interstate standards, it is one of the few non-interstate designated highways in Pennsylvania with a posted speed limit of 65 mi/h for a considerable distance.

Pennsylvania Route 3: Pennsylvania Route 3 (PA 3) is a 24.3 mi state highway located in the southeastern portion of Pennsylvania.  The route connects U.S. Route 322 Business (US 322 Bus.)  in West Chester with PA 611 in Philadelphia.  The route begins in downtown West Chester and heads east out of town as a one-way pair of streets.  Between West Chester and Upper Darby Township, PA 3 follows a four-lane divided highway known as West Chester Pike through suburban areas.  Along this stretch, the route passes through Edgmont, Newtown Square, Broomall, and Havertown.  The route has an interchange with Interstate 476 (I-476) between Broomall and Havertown.  Upon reaching Upper Darby, PA 3 heads into Philadelphia along Market Street.  In Philadelphia, the route follows multiple one-way pairs, running along Chestnut Street and Walnut Street in West Philadelphia before heading into Center City Philadelphia along Market Street and John F. Kennedy Boulevard and ending at Philadelphia City Hall.

It sits along Philadelphia Avenue (Pennsylvania Route 73) near Bartman Avenue, close to Pennsylvania Route 100.  Two buildings are located on the property: a lowercase "t" shaped main building and an "L" shaped (and smaller) enclosed flea market building.

The "main" building is heated during winter, and utilizes a fan-circulation and heat extraction system during the warmer months of the year.
