Bicycles can cost $1,200 or more, but many people are choosing to ride them on highways instead of the city streets.
Now, a team of engineers has come up with a plan to put bikes on city streets for as little as $3.1 billion a year.
The plan, proposed by the National Park Service, could save more than one-third of the $7 billion in bike-related road repair and maintenance costs annually.
“It’s really a win-win for everyone,” said Jim McElwain, chief of staff to Park Service President Donald Trump.
The park service has proposed building a $1.2 billion bike corridor, which would have a $2.6 billion cost savings over the next decade.
The federal government has allocated $1 billion over the past five years for a bike-friendly city, McElWain said.
The bike lanes would be built in six areas in the United States: Philadelphia, Boston, Detroit, Los Angeles, Chicago and San Francisco.
The project is expected to be completed in 2019.
The bicycle project is part of Trump’s plan to reduce pollution and traffic, the park service said.
The president has said he wants to build the bike-free streets in the first 100 days of his presidency.
On Sunday, Trump signed an executive order that would give the National Parks Service more flexibility to develop, fund and implement projects for bike lanes and bike paths in the U.N. headquarters complex.
The National Park Foundation said it has $9.4 billion in existing funding for bicycle infrastructure projects in the park system.
It has also committed to more than 1,000 miles of protected bike lanes, the foundation said.
It is funding a $5.5 million project to build a bike bridge connecting New York City to Washington, D.C., that would connect the two cities.
The U.K. has also put forward a proposal to build three miles of bike paths along its borders.
Other cities have already started construction on bike lanes.
Portland, Ore., is constructing a protected bike lane that will connect the city’s downtown with its industrial district.
It will be built over a protected pedestrian pathway, which was built last year in Minneapolis, and protected bike paths that will run alongside Interstate 94 and the Green Line.
New York City plans to have two protected bikeways that will cross the East River from the Hudson River to Times Square, and the city is spending $200 million on a third, which will be a protected crosswalk in Times Square.
