Found an alternative route that avoids the ridiculous Bendemeer junction on my commute to Kallang.
From Upper Serangoon Rd, turn into Wan Tho Ave and use these small roads to reach Macpherson Rd where the Royal Sporting House building is. From here, I will still need to go through the construction detour, however, I need not filter lanes and can stay on the left side.
Just need to watch out for the PIE exit when approaching Bendemeer Rd.
On the subject of commuting, anyone noticed that they're paying quite a bit more for the bus fares? My bus fare to school has increased by 25% since SBS changed to the new distance fare rates on 3rd July.
