North–South Expressway northern route
The North–South Expressway northern route is an interstate controlled-access highway running parallel to the northwestern coast of Peninsular Malaysia. The expressway forms the north section of the North–South Expressway, passing through the northwestern states of Kedah, Penang, Perak and Selangor. The expressway begins at the Bukit Kayu Hitam checkpoint in Kedah where the Malaysia–Thailand border lies, and ends at Bukit Lanjan in Selangor where the expressway interchanges with the New Klang Valley Expressway. The expressway is operated by PLUS Expressways.
The expressway runs in a north–south direction close to the northwestern coast of the peninsula, connecting several major towns including Alor Setar, Butterworth, Taiping, Ipoh and Rawang while also providing access to several rural villages on its path. The expressway runs parallel to the existing Federal Route 1; it is also concurrent to the expressway from Bukit Kayu Hitam to Jitra. The ticket system is used for toll collection between the Hutan Kampung and Sungai Dua toll plazas, and also from the Juru toll plaza up to Bukit Lanjan, where the toll collection system merges with that of the New Klang Valley Expressway. The section from Sungai Dua to Juru in the state of Penang is toll-free due to heavy usage by local commuters.
Route description
The expressway begins at the Malaysia–Thailand border at Bukit Kayu Hitam in Kedah, where the road continues as Phetkasem Road in Thailand. The expressway proceeds southwards through the states of Kedah, Penang, Perak and Selangor, where it terminates at its interchange with the New Klang Valley Expressway, also designated as route E1. While kilometre readings are taken from north to south, exits are numbered in reverse, from south to north. PLUS Expressways, previously Projek Lebuhraya Utara–Selatan formed in 1986, operates and maintains the expressway. The concession is scheduled to end on 31 December 2038.Bukit Kayu Hitam to Sungai Dua, Butterworth
The expressway begins at the Bukit Kayu Hitam checkpoint in Kedah, where across the border in Thailand the road continues as Phetkasem Road. The expressway proceeds southwards concurrently along the old Federal Route 1, which has not been upgraded and is still a limited-access road. The first grade-separated interchange, which is with route 194, provides access to the northwestern state of Perlis. The route then enters the heart of the town of Changlun, where it intersects with a few local roads with traffic lights. South from the town are several rural villages with residential roads intersecting with the expressway.Just to the north of the town of Jitra, route 1 continues southwards while the expressway bends southeast to bypass the said town, marking the end of the concurrency and the start of the controlled-access highway proper. Just to the east of the town is the Jitra Toll Plaza, where a one-time payment is made. After the toll plaza the expressway continues southwest, entering the district of Kota Setar and interchanging with route 1 near Kepala Batas. Shortly south is the Hutan Kampung Toll Plaza, where ticket tolling begins. The expressway runs east of the city of Alor Setar, where it makes two interchanges with the Sultanah Bahiyah Highway, both leading to aforementioned city.
Past the city, route 1 returns to run parallel to the expressway, both running southeasterly to enter the district of Pendang, where the expressway interchanges with a local route leading east to the town of the same name. Proceeding southeast, the expressway enters the Kuala Muda district. It interchanges once in Gurun, bends southwest, then interchanges twice again near Sungai Petani, once to the northeast of the town and once to the southeast. The expressway crosses the bridge over the Muda River, which marks the border between the states of Kedah and Penang. The expressway reaches the town of Bertam, where route 1 deviates westwards from parallelism with the expressway. Further southwest is the Sungai Dua Toll Plaza, where the ticket system ends and the toll-free section begins. The expressway interchanges south of the plaza, just to the west of Sungai Dua. This interchange marks one terminus of the Butterworth Outer Ring Road, which goes west towards Bagan Ajam. After this interchange the expressway widens to six lanes and the urban speed limit of 90 km/h applies. The expressway then crosses the Perai River.
Butterworth and Bandar Baharu
From this point the expressway enters Seberang Perai Tengah, running southwesterly along the east side of Butterworth, where it makes several important interchanges, including Jalan Permatang Pauh leading to Permatang Pauh, the Butterworth–Kulim Expressway towards Kulim and Gerik in Kedah, expressway 17 and route 1 in Perai as well as the Penang Bridge towards the island and capital. Here the expressway bends southeast away from the coast, going towards and interchanging at the Perai Industrial Area and Juru. After Juru, the road narrows back to four lanes, followed by the Juru Toll Plaza, where the second ticket system begins. The expressway then enters Seberang Perai Selatan.The expressway interchanges with route 149 at Bukit Tambun, connecting several industrial areas nearby. Close by at Batu Kawan, the Sultan Abdul Halim Muadzam Shah Bridge terminates on this expressway, connecting Bandar Cassia as well as the southwest district on the island. The last interchange in Penang is with route 1 at Jawi. The expressway then briefly re-enters the state of Kedah to interchange at Bandar Baharu, serving itself, Parit Buntar just across the border at Perak, as well as the rest of southernmost Kedah.
Alor Pongsu to Ipoh
Across the Kerian River is the Kerian district in Perak, where a new interchange with route 147 at Alor Pongsu is being constructed. The expressway then briefly winds eastwards, then southwards, to meet Bukit Merah. The expressway continues directly southwards into Larut, Matang dan Selama, interchanging again with route 1 as well as 3146 to the northwest of Taiping. Gently, the expressway winds southeast towards Changkat Jering, where it interchanges with route 60. From here, the expressway heads east through a cutting where the expressway and route 1 briefly run side-by-side. The route continues towards the district and town of Kuala Kangsar, interchanging at the terminus of route 76, which plies the rural areas of central northern Perak.At this point route 1 deviates northwards to go around a hill that is part of the Tenasserim Hills cluster. The expressway proceeds towards the hill, going across the Perak River below the Sultan Azlan Shah Bridge. After the river the expressway goes uphill, through the Menora Tunnel that is about long, then downhill into the Kinta Valley. Here, the Ipoh local-express system, constructed in 2008, begins, where all traffic bound for Ipoh or its vicinity is segregated. Southbound commuters entering the local lanes pay the toll/tap out of the ticket system at the Ipoh North Toll Plaza, while northbound motorists merging in from the local lanes collect the ticket/tap into the system. Proceeding southeast through the heart of Ipoh, the expressway's local lanes interchange with several local roads as well as route 1, which begins to run parallel to the expressway again. The system ends to the south of Tambun, where commuters on the southbound local lanes collect their tickets or tap into the system at the Ipoh South Toll Plaza, while northbound motorists entering the local lanes pay their tolls.
Simpang Pulai to Bukit Lanjan
Leaving the city, the expressway bends southwest to close the gap between the two parallel routes, effectively interchanging with the route at Simpang Pulai. Bending back southeast the expressway interchanges again with route 1 at the town of Gopeng after crossing into the Kampar district. The expressway then cuts through another hill, passing by Gua Tempurung. The cutting ends in the Batang Padang district just before the next interchange at Tapah with route 59, which connects directly to Cameron Highlands. Heading southwards, the expressway interchanges with a local road at Bidor. Further south within the same district, the expressway interchanges with route 1 thrice – at Sungkai, Slim River and Behrang.While going southeast, the expressway crosses the Bernam River into the state of Selangor. Despite this, the next interchange, the final one with route 1, mainly serves Tanjung Malim over in the previous state. From this point, route 1 leaves the vicinity of the expressway as the expressway goes southwards and the federal route goes southeast. The expressway interchanges with several rural roads at Lembah Beringin, Bukit Tagar, the Bukit Beruntung industrial area and at Sungai Buaya. Going southwards, the expressway leaves the Hulu Selangor district into the Gombak district, where it interchanges near the Rawang industrial area with route 3209. Shortly after, the Guthrie Corridor Expressway begins as an interchange on this expressway. On the last segment, the expressway interchanges with a road next to the Sungai Buloh Hospital, crosses into the Petaling district, interchanges with the Sungai Buloh Highway at Sungai Buloh, and finally terminates at its interchange with the New Klang Valley Expressway near Segambut in the north-western part of the Federal Territory Kuala Lumpur.
