The.Chesapeake.and.Ohio.Canal. (C&O.Canal),. extending. from.Washington,.DC. to.Cumberland,.Maryland,. is.one.of. the.most.popular.parks. in. the.National.Park. System..Each.year.thousands.of.park.visitors.use.the.park’s.towpath.to.bike,.hike,. jog,. and. ride. or. otherwise. use. this. park.. But. the. use. of. this. park. is. very. dependent.on. towpath.continuity..And. towpath.continuity. is.dependent.on.maintaining. and.rehabilitating.the.twelve.aqueducts.along.the.canal..Collapse.of.one.or.more.of. these.historic.aqueducts.would.severe.the.canal’s.towpath.and.would.greatly.limit. the.public’s.enjoyment.of.this.park..This.fact.had.led.to.intensive.efforts.to.preserve. and.rehabilitate.these.175-year.old.structures.
