Lock and Dam No. 2 (Hastings)
Minnesota
An elevated public observation deck puts you at eye level with towboats being raised and lowered more than 10 feet through the lock chamber, while bald eagles, American white pelicans, and cormorants work the churned-up tailwater below year-round.
Why Roamward picked it
The northernmost lock-and-dam viewing stop on the corridor, just southeast of the Twin Cities on US-61/MN-61 -- an easy, free, no-appointment detour that turns the start of the drive into an immediate hands-on river-engineering stop.
