The number of Americans who commute has nearly doubled since 2005, according to the League of American Bicyclists' 2014 American Community Survey data report. As numbers continue to grow, finding places to park all those bikes is becoming increasingly important. Here's a look at four innovative plans.

Stockholm, Sweden  Writer Adele Peters recently profiled a 700-bike garage project in Stockholm for Fast Company, According to Peters, city officials are planning the bike-only garage near a major train station and it will include a bike repair shop, helmet lockers, and changing rooms with showers–allowing commuters to change and freshen up before work.

"The city of the future is not one built around the car as a means of transportation," says Roger Mogert, city planning commissioner for Stockholm. "This requires that we make it easier to travel by bike, and of course arranging for safe and efficient parking solutions is on step towards that goal."

Salem, Mass.  The Salem, Mass., MBTA station will feature a Pedal & Park, essentially a multi-tiered cage allowing commuters to safely stow bicycles before boarding the train. According to NOBO magazine:

Pedal & Parks already exist in several locations, chiefly at T-stops and busy transportation hubs, though Salem is the first of these locations to include only access to MBTA bus and commuter-rail ... “Safe and convenient bike parking at Salem Station makes bicycling an attractive option for more people to get to the train without driving,” said MassBike Executive Director David Watson. “One of the obstacles that prevent people from biking to transit is the lack of secure bicycle parking. No one wants to get off the train at the end of a long day only to find their bike missing or vandalized.”

Amsterdam, Netherlands  In Amsterdam, officials have come up with a plan to construct what amounts to an underwater bike parking garage. According to The Atlantic:

The city has just announced a plan to excavate a 7,000-space bicycle garage under the Ij, the former bay (now a lake thanks to the construction of the Afsluitdijk barrier) that forms Amsterdam’s waterfront. The lake forms a sort of moat around the city’s Central Station, its main transit hub and a place where it could be possible to connect a subaquatic bike catacomb directly via tunnel to the city’s metro system. Stacking a total of 21,500 new bike spaces around the station by 2030, Amsterdam also plans to create two new floating islands with space for 2000 bikes each ...This might seem like a pretty grand infrastructure overhaul just to stow a few bikes, but Amsterdam’s cycling statistics are phenomenal. A massive 57 percent of Amsterdammers use their bikes daily, with 43 percent of them commuting to and from work using pedal power.
