The famed Hollywood sign, a worldwide symbol of Los Angeles, could become a lot easier to reach in the future if a proposal for a mile-long aerial tramway up the mountains is approved.

Warner Brothers movie studio on Tuesday, July 10, announced details of a proposal to build a tramway from its Burbank film lot up the steep sides of Mount Lee to the sign.

Warner Bros said it would pay for the design, construction, operation and maintenance of the proposed Hollywood Skyway. It declined to comment on a report in the Los Angeles Times that the project would cost about $100 million.

The 44-foot-high (13.4 m) white Hollywood letters, originally created in 1923 as an advertisement for a real estate development, are a designated historical monument. But there is no easy way to get there, apart from a rugged hike from nearby Griffith Park, and tourists often clog surrounding neighborhoods trying to find ways to reach the sign.
