CR 537 begins at an intersection with CR 737 in the downtown area of Camden in Camden County, heading east on four-lane undivided Federal Street. West of this intersection, Federal Street continues to the Camden Waterfront on the Delaware River. The road runs east passing a few parking lots, turning into a one-way eastbound street at 3rd Street. CR 537 Spur (Market Street) to the north is one-way westbound, serving as the westbound direction of CR 537 through downtown Camden. From here, Federal Street passes downtown businesses as it alternates between two and four lanes, crossing New Jersey Transit's River Line at the 5th Street junction. The route intersects CR 551 and the northern terminus of CR 561 before coming to an interchange with I-676. After this, CR 537 Spur merges onto CR 537 and the road becomes two-way and two lanes wide as it passes under a railroad line that carries Conrail Shared Assets Operations and the River Line. The route interchanges with US 30 and crosses the Cooper River and intersects CR 543. The road passes through urban areas of businesses and industry, crossing CR 601 and becoming lined with businesses. CR 537 comes to junctions with CR 610 and CR 609 as it heads into more residential areas, intersecting CR 611. At this point, the road becomes the border between Pennsauken Township to the north and Camden to the south, meeting CR 663.

At a point shortly before the intersection with CR 644, CR 537 becomes the border between Pennsauken Township to the north and Cherry Hill to the south. Shortly after this crossing, the road heads through more residential surroundings.

Upon intersecting Centerton Road, the route turns north as a four-lane divided highway and heads through fields, crossing the railroad tracks and continuing into Mount Laurel Township. At the CR 614 junction, CR 537 turns southeast as a two-lane undivided road, turning east and running parallel to the north of the Conrail tracks again as it passes under I-295 and the New Jersey Turnpike, within a short distance of each other. The road heads through a mix of farms and homes as it crosses CR 686 before continuing east into areas of residential subdivisions as it crosses CR 635.
