Parts of the nearly-finished tunnel connecting Khao Yai National Park with Tap Lan National Park on Prachin Buri-Nakhon Ratchasima Highway 304, are set to open for temporary use during Songkran holidays to ease expected traffic congestion.
Millions of people are expected to hit the road during the Songkran period for vacations or visits home. Traffic flows during the period, as a result, usually move at a snail’s pace.
In the hope of easing traffic congestion, Prachin Buri provincial highway office has planned to open the tunnel from April 10 onward.
“It should help with the traffic flow along the 30-kilometre stretch of Highway 304 between Na Di district of Prachin Buri and Wang Nam Khiao district of Nakhon Ratchasima,” the office’s chief, Apichart Boonyoung said over the weekend.
Construction of the tunnel and an elevated bridge between kilometre markers 192 and 195 has resulted in the closing of two of the four traffic lanes, leading to heavy traffic congestion.
If the parts of the almost-finished tunnel were not opened for use during the Songkran 2018, Apichart predicted a traffic nightmare would occur.
“We will conduct a trial run before opening the tunnel to the public,” he said.
