Johnson Trolley Line north

Denow Road, Lawrence Township, Mercer County, New Jersey


NJ Turnpike to exit 7A for US 195 west; take US 295 north to US 95 heading toward Pennsylvania; get off at Exit 7 for Route 206 north; in a short distance turn left onto Franklin Corner Road (Route 546); take the first left turn onto Denow Road; drive 0.3 of a mile; the obscure southern entrance for the trail is on the right just before reaching Melvina Drive.  You can park on Melvina Drive and walk back to the path opening set amidst woods edge making it somewhat hidden.

For the northern entrance;  from Route 206 north; turn left onto Gordon Road; parking is on the right around James Street on the left  (I don't know exactly where it is.)


5/05/2005.  Compared to other rail-trails, canal trails, this trail is through a much more built-up area.  There are house backyards on both sides of the trail with some of the backyards coming straight back flush with the trail (without any intervening hedges).  There are also quite a few streets to cross, one of them very busy.   There are also a lot of horticultural species on both sides of the trail. In other words, it is far from a natural area.  Dr. Patrick L. Cooney.
