The Indianapolis Cultural Trail: The Next-Gen in U.S. Protected Bike Lanes from Streetfilms on Vimeo.

A labor 15 years in the making, Indy's Cultural Trail (which includes 1.5 lane-miles of on-street protected bikeways) shows how physically beautiful a great on-street bikeway can be — and how a first-rate facility can stimulate real estate development nearby: more than $100 million by the time it officially opened in May. No wonder Mayor Greg Ballard, a Republican, has been known to stop by the city bike coordinator's office to ask, "What's next?"

3) Guadalupe Street, Austin

The half-mile spine of Austin's university district is now one of the country's best examples of a complete street, with pedestrian-friendly shops, bus stops and a first-rate bike facility that connects to other lanes in an integrated network. In a time when many U.S. cities still ban comfortable biking from busy commercial corridors, Austin is showing why they're actually a perfect match.

4) Fell and Oak Streets, San Francisco

They run for just a quarter mile each, but for San Franciscans, these lanes make all the difference for a couplet of much-traveled roads that also serve as crosstown arterials for cars. Removing auto parking here was the key to a low-stress connection between Golden Gate Park and The Wiggle, the old riverbed that is now the city's most popular east-west bikeway. Plans for more permanent planters are in the works.

5) Linden Avenue, Seattle

Seattle's philosophy on protected bike lanes is influenced by its northern neighbor, Vancouver BC: do them up nice the first time, with an artful combination of posts, low concrete curbs, drainage ditches, dedicated traffic signals and plentiful painted markings. There's no better example of that than Linden Avenue, a useful connector in a far-north neighborhood that Seattle Bike Blog (maker of the video above) rightly called "world class."

6) First Avenue, New York City

When Mayor Michael Bloomberg tried to reverse course on a plan to add great bike lanes to upper First and Second Avenues, East Harlem didn't stand for it. "I pay my taxes like everyone else, and we deserve the same treatment north of 96th Street," resident James Garcia testified. With the help of City Council Member Melissa Mark-Viverito, good sense prevailed. First Avenue now has a protected bike lane from 72nd to 125th Streets. "I’m not only a cyclist but a mom with four kids who all cycle, and also a driver. It makes complete sense," said Peggy Morales, who chaired the committee that recommended that the lanes replace 166 on-street parking spaces. "We should be able to go cycling without having to take our lives into our own hands." Yep.

7) Milwaukee Avenue, Chicago

The success of Milwaukee Avenue's new mile or so of better bike lanes, which combine physically protected lanes with stretches buffered by paint, is a lesson to planners: the best place to put a buffered lane isn't necessarily where you wish people would pedal, but where they're already pedaling. It's the same principle as sidewalks, which are built along desire lines that people naturally carve out. Biking is so important to Milwaukee Avenue that when this project came under fire, three local retail joints on the corridor piped up in its defense.

Maybe because it's been stuck for years in some of the worst traffic in the country, the capital of the New South is turning out to be a fertile ground for big bike improvements. Early this year, Mayor Kasim Reed turned heads around the country by promising to double Atlanta's bike lanes by 2016. The protected bikeway on 10th Street, which opened a few months later, was the first of its kind in the entire Southeast and promises to be a model for more.

9) Cherry Street, Seattle

Any other one-block uphill stretch of protected bike lane beneath a highway viaduct, one block from the second-tallest building on the West Coast, would be nothing more than a pretty good idea. But Cherry Street's protected bike lane makes our list because of who suggested it: a pair of anonymous safety-minded community members calling themselves the "Reasonably Polite Seattlites" who spent $350 of their own money to install these bollards in the dead of night, then sent the city an email to explain why. The coolest thing of all: after removing the temporary installation, city planners realized the activists were right and installed a proper version themselves.

Here's the most remarkable thing about this protected bike lane, Memphis's first: In 2010, this city didn't have a single bike lane of any kind. In the three years that followed, this storied city on the Mississippi has made a new name for itself by making advanced bike lanes like this one standard on all new repaving projects of its majestically wide thoroughfares. The first great song about biking in Memphis? Only a matter of time.

The Green Lane Project is a PeopleForBikes program that helps U.S. cities build better bike lanes to create low-stress streets. Correction: An earlier version of this post confused "avenue" with "street" in Atlanta and New York.
