Jalan Tengah is the of both the main road as well as residential neighbourhood in Bayan Baru, Penang. It is also one of the oldest roads in the area, having existed since the early part of the 20th century. It got its name, which means "middle road", from its location it was the only road that went across the paddy fields of the then Sungai Nibong, linking Bayan Lepas to Sungai Ara. At that time, Bayan Baru has not yet appeared on the map.
Today everything is different, and Jalan Tengah has become one of the busiest road in the township. From a small two-lane country road, it has grown to four lanes thoroughfare. In the early part of the 21st century, urban development in the area resulted in road realignment that fragmented Jalan Tengah into two parts. The eastern segment runs from Jalan Sultan Azlan Shah to Jalan Tun Dr Awang, where it meets the newly created Jalan Bayan. A rump portion of Jalan Tengah continues from Jalan Tun Dr Awang to Jalan Dato Ismail Hashim. The two segments are not directly connected.
The traffic along Jalan Tengah has increased over the last four decades. From a simple two-lane road, Jalan Tengah has grown to four lanes. Still, it is quite congested especially during the morning and evening rush hour. Much of the traffic along Jalan Tengah is from motorists passing through the area between the Bayan Lepas Free Trade Zone and Sungai Ara, Relau and Paya Terubong.
