The bridge is 1,170 meters (0.73 mi) long. It has two 3.5 m (11 ft 6 in)-wide road lanes, two 1.5 m (4 ft 11 in)-wide footpaths and a single 1,000 mm (3 ft 3+3⁄8 in) gauge railway line in the middle, straddling the narrow central reservation.
The bridge was designed and built by Australian companies as a demonstration of their ability to complete major infrastructure projects in Southeast Asia. The concept design of a balanced cantilever bridge was proposed by Bruce Ramsay of VSL with the final design carried out by Maunsell consulting engineers.[citation needed] It was built by John Holland.[3]
The official name of the bridge was changed, with the addition of "First" after the opening of the Second Thai–Lao Friendship Bridge further south at Savannakhet in January 2007.
Road traffic
Traffic on the bridge drives on the left, as in Thailand. Traffic in Laos drives on the right. The changeover at the Lao end, just before the border post, is controlled by traffic lights.
A shuttle bus service operates across the bridge, between the Lao and Thai border posts.
Bicycles and tricycles can travel on either the road or the footpath, while pedestrians can walk directly on the footpath.
A meter gauge rail track from Nong Khai station runs along the central reservation of the bridge. Road traffic is stopped when a train is crossing.
In March 2004, an agreement between the Thai and Lao governments was signed to extend the railway to Thanaleng Railway Station in Laos, about 3.5 km (2.2 mi) from the bridge. This was the first modern railway link to Laos, as a short portage line once existed. The Thai government agreed to finance the line through a combination of grant and loan.[4] Construction began in January 2007.[5] Test trains began running in July 2008.[4] The formal inauguration occurred on 5 March 2009.[6]
A US$50 million loan was reportedly received from the Thai government for the extension. Construction was originally slated to begin in December 2010. Lao railway officials confirmed as late as September 2010 that plans would go ahead. The extension, which would have taken an estimated three years to complete, would have stretched 9 km (5.6 mi) from Thanaleng to a new main Khamsavath Station.[8] The station will be completed by June 2022, and open 2023.
Since February 2010, the Eastern and Oriental Express crosses the Mekong via the bridge into Laos.[9] There is currently no connection to the China-Laos Railway. The standard gauge line circles the north east of Vientiane, to a depot just 2 km from the Friendship Bridge. A new bridge is proposed from this point, to join the proposed Thai High speed line at Nong Khai station just south of the Mekong.[10]
