陸橋 ― overpass; flyover

昨日に引き続き、道路の用語です。

日本語では陸橋、立体交差、高架橋、跨線橋、など様々な呼び方をしますが、英語では、overpass（アメリカ英語）、flyover（イギリス英語）という表現がそれらを総括します。


overpass
n. 1. A passage, roadway, or bridge that crosses above another roadway or thoroughfare
(American Heritage Dictionary of English Language.)


という定義からは、いわゆる日本の歩道橋もこれにあたるのですが、アメリカ英語やイギリス英語のそれは、主に、ハイウェーで幹線道路の上をまたぐ形で建設されている道路のことを指すようです。


SAN JOSE, Calif.—A man has been arrested after authorities say he kidnapped his ex-girlfriend and their 11-month-old baby in San Jose, led authorities on a 75-mile chase and then jumped off a freeway overpass.

San Jose police Officer Jose Garcia says the woman and child were forced into a pickup truck in the Overfelt neighborhood Saturday night.

The San Jose Mercury News says a nearly two-hour chase began that involved several freeways and continued through Daly City, Colma and Woodside before the driver intentionally crashed on Interstate 280.

Garcia says the driver briefly held the woman at knifepoint, then leaped off a freeway overpass and landed 30 feet below.

BRACKEN RIDGE: Work on a flyover at the Telegraph Rd level crossing at Bracken Ridge is unlikely to start before 2016, despite plans for a bus station next to the crossing as part of the Northern Busway.

On Tuesday a traffic camera captured a near miss between a train and a vehicle, prompting additional concerns about the safety of the crossing.

A spokesman for Transport Minister Rachel Nolan did not rule out motorists having to wait until 2026 - the proposed year of the completion of the busway - for a proposed flyover at the crossing.
