Current developments Kuala Lumpur-Penang Through Traffic (Ipoh North (Jelapang) - Ipoh South local-express lanes) The Jelapang and Ipoh South toll plazas would be demolished in 2009 to make a non-stop route across Ipoh. This is achieved through the construction of two local-express lanes for each side, which are only accessible via Exit 138 Ipoh South Exit (for northbound traffic) and Exit 141 Ipoh North Exit (for southbound traffic). The toll plazas in Ipoh are therefore relocated at each ends of the local-express lanes. The decision to demolish both toll plazas was made as a result of accidents which happened at Jelapang toll plaza. Since the toll plaza was opened on 28 September 1987, there were many accident cases which involved brake failure in heavy vehicles due to hard braking when proceeding downhill to the toll plaza. On 7 June 2008, the new Ipoh North toll plaza (South bound) replacing old Jelapang toll plaza opened to traffic, followed by north bound on 15 August 2008. Beginning 11:00 am on 14 July 2009, the Kuala Lumpur-Penang through traffic is now opened to traffic. With the opening of the between Ipoh North (Jelapang) and Ipoh South stretch, highway users are no longer required to stop for toll transactions at the Ipoh North and Ipoh South Toll Plazas.~ The runaway truck ramp is also provided in two locations in Jelapang and Menora.
