BUTTERWORTH-KULIM EXPRESSWAY INTERCHANGE (BKE IC)
The Butterworth-Kulim Expressway Interchange (BKE IC) is one of the busiest junctions in Seberang Perai, with traffic volumes at the at-grade signalised roundabout as high as 10,000 passenger car units (PCU) per hour during peak traffic.
The highest turning traffic volume was observed to be the northbound right-turn from the North-South Expressway (NSE) to BKE.
A third-tier one-way flyover is proposed for this turning movement, which will help reduce the overall traffic volume entering the roundabout by some 20%.
Operation of the signalised roundabout will then be improved with shorter cycle (waiting) times.
This component is still a proposal and subject to approval and changes in the future.
