The final electrical systems are being installed, with the contractor promising to have the work done by midnight Thursday (May 30), in line with the extended contract, Phuket Highways Chief Somwong Lohanut explained to The Phuket News.

“We will not open the tunnel after midnight on May 30 because it would be too dangerous for drivers,” he said.

“We will make sure all the systems are working, especially the electrical systems inside tunnel, in the morning on May 31,” he added.

Once the final checks are complete, the underpass will be opened to motorists, he said.

Chief Somwong confirmed that the underpass will open with one lane for traffic in each direction, with only orange plastic poles as lane dividers.

After confirming that each lane is 3.5 metres wide, lanes Chief Somwang assured that the lanes are wide enough for tour buses to pass in each in opposing directions.

“We are sure that tour buses can pass inside the underpass as the width of the lanes are international standard,” he said.

Somkiet Yimpong, Project Manager at the Phuket office of the Highways Department, explained that construction of the overall project, including decorative features, is about 98% complete.

“Now we are installing some security systems. Once the security system is complete, we will open the Chalong Underpass to traffic on May 31,” he confirmed.

However, Mr Somkiet allowed for some last-minute delays in his assurance the tunnel will open this weekend.


“The contractor has promised that everything will done on May 30, but I will need to inspect the construction. If I find that any defects making the tunnel unsafe or not secure, the contractor will have to fix the construction,” he said.

“I will confirm on May 30 whether or the Chalong Underpass will open to traffic or not, but only after I have completed my inspection,” he said.

Mr Somkiet also pointed out, “The Chalong Underpass is not the same as Phuket Airport Underpass or the Bang Khu Underpass. The Chalong Underpass tunnel is 350m long and the road is curved.

“The Phuket Airport Underpass tunnel in only 160m and it is straight, giving motorists a clear view through the tunnel from beginning to end. So with the Chalong Underpass we cannot have workers complete the finishing touches in the tunnel while opening one lane of the underpass to motorists at the same time.

“We must wait for everything to be done and the security system completed before we open the Chalong Underpass to traffic. If we opened it now, accidents will happen,” he said.

The golden lotus tower, being built in the middle of Chalong Circle at a cost of B3 million as part of the overall B546mn budget for the entire underpass project, will also be completed by week’s end, Mr Somkiet assured.

The tower features a sculpture of a lotus bulb, a Buddhist symbol of peace, as its crowning glory.

“The construction of the golden lotus tower isn’t finished just yet. We must finish painting it and complete a lot of detail, but it will be finished on time on May 30,” Mr Somkiet said.

What are the help- and rescue services thinking of this Chalong underpass? Are there drills done?  The Chalong first aid station next door not gives comfort, that is still not a hospital. Perhaps this Chalong Underpass should be closed at night from 10 pm till 6 am. The normal roads around the circle easily can handle the little traffic flow during that period of time.

Kurt | 30 May 2019 - 12:38:22

Perhaps the width of the lanes is according international standards, but the underpass in total is not!
A missed chance is speed limitation by having at in/out locations good speed humps. And because the road is curved ( no anticipation on happenings ahead possible) a speed limit of 40 kmh would be good.

only one lane in each direction? A site for many accidents I think

Kurt | 29 May 2019 - 21:08:40

Busses, all kind of trucks and trailers should be banned from this narrow underpass. Just normal cars only, that gives more chance that this underpass not becomes one day a death trap when a serious accident happens.  Are there boxes with fire hoses connected to water piping under pressure in this underpass?

Asterix | 29 May 2019 - 17:17:34

They will open the Chalong Underpass without a first accident and disaster drill which is scary.
Without cement blocks to separate the opposing lane, Chalong Underpass death-trap will open soon and it is a question of time before trucks, large buses, double-decked buses, minibus, pick-up trucks will collide head-on with tragic consequences about deaths and possibly vehicles in fire.

Agreed.   Concrete Dividers should have been mandatory.  Unfortunately my bet is that there will be an accident within 3 days. It's too bad really.   When they finally put the concrete dividers up the buses won't be able to pass each other.

Kurt | 29 May 2019 - 15:14:56

With no concrete lane dividers it is waiting for a accident to occur by some lunatic or drunk 'over taker'. Fingers crossed.  In less than 3 months many of these plastic dividers will be knocked away, as it happens everywhere on Phuket's even much wider roads.  This underpass is not suitable for large tour busses and large truck trailers.  Safety first.

Should be very int and see how many hours the tunnel is open before an accident occurs inside the tunnel without having divided the roadways with concrete.
