EUGENE, Ore. -- A hidden BMX track near Eugene's Franklin Park and Interstate 5 has allegedly been there for decades, and very few people have heard about it.

The track was built by hand on Union Pacific Railroad property and provides a huge layout for mountain bikers and BMX riders to use directly next to the Willamette River.

Eugene Parks officials say police have responded to many calls at the bike track over the years.

"They told me it was all handmade 'cause they couldn't get machinery down here, so I thought that was cool and impressive. It's mostly for BMX riders but some people use mountain bikes on it too," said a homeless resident living near the track.

The track is illegal, but so far there have been no repercussions for trespassing on the railroad's property.

People at the track told KEZI 9 News that the community that uses the track tends to keep it clean and pick up trash in the surrounding areas, while also continuing to rebuild the dirt jumps.
