I haven’t spent a ton of time in Portland Maine, but it seems like everytime I do, I notice this one spot of town. Unfortunately, I always see it from the fast lanes of I-295 as I head north. I finally stumbled upon it again while riding my bike on the Bayside Trail, which runs along 295 from the Eastern Promenade Trail to the Back Cove Trail.
Nestled underneath the south bound off ramp for Rt. 26 is a bank with an extra addition of concrete. Judging by the height of the kicker, the tire marks, the roughness of the extra concrete, I would say this was done for BMX riders, not skateboarders.
