Malaysia's road network
covers 250,023 kilometres (155,357 mi), of which 248,067 kilometres
(154,142 mi) is paved/unpaved roads, and 1,957 kilometres (1,216 mi)
is expressways. The longest highway of the country, the North–South Expressway, extends
over 800 kilometres (500 mi) between the Thai border and Singapore. The
Second longest highway is East-Coast Highway (LPT-E8) Spanning almost
500 km from Kuala Lumpur to state capital of Terengganu, Kuala Terengganu.
The road systems in Sabah and Sarawak are less developed and of lower quality
in comparison to that of Peninsular Malaysia.
Expressways: the main north-south motorway has number E1
from Thailand to Kuala Lumpur. Between Kuala Lumpur and Singapore it is the E2.
Other roads do not have a clear system, and 2-digit numbers can be more
important than some 1-digit numbers.
Exit numbers are uniqe throughout the country. For example, exits on the E1
have numbers 1001, 1002 etc., exits on the E35 have numbers from 3501.
National roads usually have 1- or 2-digit numbers. There are only a
few numbers over 100. Higher numbers tend to appear in clusters, but there is
no clear zone system. For example, the numbers 89 - 96 and 99 are all close
together in the south of Johor, but 87, 88 and 98 are in Pahang. Odd numbers
are often used for north-south routes and even numbers for east-west routes
(this holds for main roads 1, 2, 3, 4 and 5), but there are too many exceptions
for this to be considered a rule.
Most states do use this rule for state roads. State road numbers begin with a
letter which is also used for general administration. This letter is often the
first letter of the state name (J=Johor, M=Melaka) but this could not be done
for all because many of the names begin with the same letter.
