The Butterworth railway station is one of the major stations along the Malayan Railway's west coast route.
As such, regular Malayan Railway services are available to other cities along western Peninsular Malaysia, including Ipoh, Kuala Lumpur, Malacca and Johor Bahru, as well as on to Woodlands in northern Singapore.
Aside from these, the Butterworth railway station is also the terminus of the State Railway of Thailand's Southern Line (via Padang Besar) and the International Express from Bangkok.
Notably, the train station is one of the main stops of the Eastern and Oriental Express service between Bangkok and Singapore as well.

In recent years, the Penang Sentral project has been underway at a site adjacent to both the Butterworth railway station and Sultan Abdul Halim Ferry Terminal.
Mooted as the main transportation hub in the State of Penang and as Penang's answer to Kuala Lumpur Sentral, Penang Sentral is intended to serve as a termini for both public bus and longer-distance intercity bus services.

Public bus services are provided by two firms - Rapid Penang and Cityliner.
Due to Butterworth's importance as a transportation hub, most of the Rapid Penang's routes originate and terminate within the town.
Rapid Penang's bus routes 601, 602, 603, 604, 605, 608, 701, 702, 703, 709 and 801 connect Butterworth with other towns within Seberang Perai, including Perai, Bukit Mertajam, Kepala Batas and Nibong Tebal, whilst the company's Intercity routes link Butterworth with Sungai Petani in Kedah and Parit Buntar in Perak.
Cityliner operates another six bus routes which link Butterworth with a handful of destinations in Seberang Perai, Kedah and Perak.

Meanwhile, the Butterworth Outer Ring Road (BORR) was completed in 2005 in order to reduce traffic congestion along the North–South Expressway east of the town, as well as facilitating traffic dispersion within Butterworth itself.
The BORR includes the Prai River Bridge, a cable-stayed bridge that links Butterworth and Perai to the south.
Another major expressway within Butterworth is the Butterworth–Kulim Expressway, an interstate highway that connects Butterworth with Kulim in Kedah.
