Finding your way around Bangkok can be a challenge. The lack of standard transliterations for Thai words means that the street names listed here will not always match those seen on street signs. Additionally, some streets are known by more than one name – for example, Charoen Krung Road is New Road and Wireless Road is Witthayu Road. Most major roads (thanons) have numerous numbered (and sometimes named) sois and troks (minor roads and lanes) leading from them. Odd-numbered sois usually lead off one side of a road, even numbers off the other. Be warned that there can be considerable distances between sois – for instance, sois 6 and 36 off Petchaburi Road are more than 2 miles (3 km) apart. Major sights, markets, and ferry piers are also listed in this gazetteer.
