In Bangkok, Thailand there are more than 5.4 km of covered wide dedicated elevated skywalks with lighting. These were developed due to lack of proper sidewalks as well as street hawkers and local merchants taking advantage of any sidewalk space as makeshift commercial real estate. Common reasons skywalks were built include to avoid street pollution, dust, wetness from food vendors and/or rain, potholes, long queues, crowds, and uneven pavement, supporting urbanism but probably most importantly, tourism receipts. Most skywalks connect to a BTS station and utilize space underneath the rail line and BTS pillar supports. These skywalks have connector ramps which connect stations to malls seamlessly and are paid for by the malls themselves, otherwise the city and BTS fund walkway development. A 50km long extension project was shelved in 2011 due to funding issues, nevertheless the system is growing organically.
