What is the longest underground tunnel in Singapore?

How long is the KPE tunnel in Singapore?

KPE: 12 km total.

Tunnel section: 9 km. Longest? Not anymore.

• Opened: 2008. Ancient history.
• Connects: ECP to TPE. Big deal.
• Underground. So what?

The crown for Southeast Asia's longest has shifted. Details are classified. Better that way, isn't it?

KPE? My daily nightmare. A 9-kilometer concrete worm. My exit: always jammed. Avoid peak hours. Save your soul.

What is the longest tunnel expressway in Singapore?

Okay, so longest tunnel in Singapore, right? It's the KPE and MCE Expressway Tunnel. Twelve point forty-six kilometers. That's a seriously long drive, man. I drove through it last year, 2024, in July. Hot as hell. My AC was barely coping. Seriously, I felt like I was in a metal oven. The air was thick, you know? Claustrophobic even, despite it being so wide. I was late for a meeting, super stressed. The whole thing felt endless.

Ugh, the traffic. It was stop and go. I swear I saw at least three accidents. Not major crashes, just fender benders, but still. Added to the general misery. My phone battery almost died. I had to use my old car charger – the one with the cracked casing! I almost had a panic attack. You never truly appreciate air conditioning until you're stuck in a hot, long tunnel.

KPE and MCE are the names. Twelve point forty-six kilometers. That's the length. Remember that? It's etched in my memory, thanks to that awful July day. I'll never forget it. Seriously, I was sweating bullets.

• Location: Singapore
• Length: 12.46 km
• My experience: July 2024, overheated car, terrible traffic, almost missed a crucial meeting.

It's way longer than I initially thought. I knew it was long, but not THAT long. It felt like an eternity. Definitely the longest tunnel I’ve ever been in. And I’ve been through some tunnels.

How many km of road in Singapore?

Oh, Singapore's roads? They're not just roads, they're like a meticulously organized plate of noodles. Over 9,500 lane-km, you say? That's like driving from my aunt Mildred’s house to, well, another part of Singapore. Seems excessive, tbh!

They're practically paved in orchids, these roads. Or maybe that's just my imagination after one too many Tiger beers.

• It is all lane-kilometers, mind you.
• Imagine painting all those lines. My back hurts just thinking about it.
• Expressways galore! Zoom zoom!
• I bet finding a parking spot is still a nightmare.

It’s like they designed the roads first, then squeezed the buildings in later. And I swear, half of them lead directly to hawker centers. Coincidence? I think not. Also, aunt Mildred likes noodles.

Aunt Mildred once told me she tried to count them. She only got to about 3, before needing a nap. Bless her heart.

So, 9,500 lane-km? More than enough to get you completely and utterly lost. Which, let's be honest, is half the fun.

How long is Bukit Timah Road?

Fifteen-point-five-three miles. A tad over twenty-five kilometers. Think of it – that's practically a marathon for a car! Longer than my commute to grandma's house, and that's saying something.

Key takeaway: It's long. Seriously long. For Singapore, at least. Think of it as the serpentine spine of a very well-manicured island lizard.

• Length: 25km (15.53 miles) – that’s almost the distance to the next dimension. (Just kidding, but still impressive).
• Significance: One of Singapore’s longest roads, named after the majestic Bukit Timah Hill. (I climbed it once, nearly perished from the humidity.)
• Fun Fact: I bet there's more street food stalls along Bukit Timah Road than grains of sand on Sentosa Beach. Okay, maybe not, but still many.

The road's length is a testament to Singapore's... well, length. I'm picturing it as a giant, paved python slithering through the city-state. A very orderly python, of course; Singapore is nothing if not orderly.

This road, my friends, this is the stuff of legends. Or, at least, mildly impressive travel stats. You know, for a small island. Don't tell the Singapore Tourism Board I said "small." They are sensitive about that.

Which is the longest expressway name?

Longest expressway name? That's a head-scratcher, isn't it?

• Pan-Philippine Highway (AH26), clocking in at a hefty 3,380 km. It's like they named it while driving the whole thing.
• National Highway 27 in India, a cool 3,507 km. Almost as long as my attempts to parallel park.
• Chile Route 5, stretching 3,364 km. Makes you wonder if they just kept paving until they ran out of Chile.

And you know what's funny? My uncle Steve's driveway feels longer than some of these on a hot summer day. Talk about perspective!

What is the speed limit in the KPE tunnel?

Okay, KPE tunnel speed... 80 km/h, got it. Damn, those digital speed cameras are savage. 24/7 watch. Imagine getting caught at like 3 AM. Is it really 80? I am pretty sure it is, but... oh yeah, saw the sign last week. I was rushing to that bak chor mee place at Bedok, you know? The one near my aunt's place.

Anyway, speed cameras. Brutal. But speed limits lower if there's a safety advisory. Makes sense, duh. Wish they'd make it, like, a flat 70, though. Safer.

• 80 km/h is the usual limit.
• Cameras run 24/7. Seriously.
• Safety advisories = lower speed.

I think I will go get some bubble tea tomorrow, maybe. Wait what were we talking about? KPE speed limit! Right.

What is the speed limit in the battery tunnel?

The operating speed in the Brooklyn-Battery Tunnel is 40 miles per hour (64 km/h). Seems straightforward, doesn't it?

The tunnel clearance is 12 feet 1 inch (3.68 m). Interesting how they specify that with such precision.

It is commonly known as the Hugh L. Carey Tunnel.

It has four lanes. How many lives have passed through there, I wonder?

• Opened: May 25, 1950.
• Location: Connects Red Hook in Brooklyn with the Financial District in Manhattan.
• Toll: Varies, but plan on swiping that E-ZPass. Gotta love it.

You see, everything has two sides.
