SUBANG’S MOST HATED ROUNDABOUT FINALLY GETTING A MAKEOVER:  MAJOR TRAFFIC UPGRADES COMING JULY 2026!

If you’ve ever found yourself stuck at the infamous Subang Jaya roundabout, the one linking SS15, SS12, SS13, and SS14 you probably know the pain of inching forward for 20 minutes just to make a single turn. For years, this iconic traffic choke point has tested the patience of even the most zen drivers. But good news is finally in sight – major upgrades are on the way to untangle the jam once and for all!

According to MBSJ MPP Zon 1 Councillor Ken Chia, a brand-new signalised roundabout traffic dispersal system has officially received the greenlight from both MBSJ and the New Pantai Expressway (NPE) concessionaire. Works are set to kick off in July 2026 and are expected to wrap up by December 2026, with operations targeted for January 2027.

The Jam We All Know Too Well

If you’ve ever tried to cross from USJ (Persiaran Kewaipan) to SS12 during peak hour, you already know what chaos looks like – cars cutting in from every direction, buses trying to squeeze through, and motorcyclists weaving around just to get across. The roundabout’s location, sandwiched between Persiaran Kewajipan and the NPE access road, makes it one of the busiest junctions in Subang Jaya.

Morning commuters from USJ heading to SS12, afternoons filled with students and hospital visitors going to SJMC – everyone seems to merge at the same spot. The result? Massive gridlock every. single. day.

What’s Changing

Councillor Ken explained that the project will roll out in three key phases targeted to smooth out the worst choke points:

• Phase 1 & 2 will cover the stretch between SS14 and SS15 near Persiaran Jengka, and also the extra U-turn along Persiaran Kewajipan near the SJMC Hospital junction. The existing U-turn from the SS14–SS15 roundabout will be widened (on both ends) to allow for easier movement before the traffic lights. Both stretches will be upgraded one at a time to minimise disruption.
• Phase 3 will kick off after the first two phases are done. This is where the magic happens. The roundabout will be turned into a signalised system complete with three sets of traffic lights to coordinate flow and reduce the usual chaos.

How It’ll Work

The upgraded roundabout will feature three sets of traffic lights to regulate the flow and keep things moving efficiently. Vehicles from SS15 or USJ heading towards Bandar Sunway will only need to head towards SJMC first, make a U-turn there before the hospital, and then continue their journey. Alternatively, drivers can hop onto the existing flyovers to get to Sunway more directly.

The Big Picture

Councillor Ken added that the entire project will be undertaken by Sunway; ensuring smoother connectivity for residents and visitors once it’s fully operational. “This plan will help reduce congestion, especially during rush hours, and improve traffic movement around the key intersections,” he said.

So, while there might be a few months of inconvenience along the way, come January 2027, daily commuters can expect a much smoother ride through one of Subang’s busiest junctions.

With this upcoming overhaul, residents can finally look forward to smoother commutes, fewer honking matches, and maybe even a few extra minutes of peace on the way to work.

Subang Jaya drivers, what do you think? Will this finally solve the roundabout jam once and for all?
