City Hall is in the midst of conducting preliminary studies to assess the feasibility of building either an overpass or an underground tunnel at the Chaom Chao roundabout in an effort to ease traffic congestion in the area.

According to Mean Chanyada, spokesman for City Hall, a technical team has been dispatched to survey the area and observe traffic conditions.

“The congestion there requires us to take action, to study if we should build a sky bridge or an underground tunnel,” he said. “We don’t know when the project will happen . . . we just conducted a preliminary study.”

Chanyada directed further questions to Ministry of Public Works and Transport spokesman Vasim Sorya, who said the project comes under the supervision of City Hall and does not involve the ministry.

“If there is a request from City Hall, we will provide technical and advisory assistance, [but] the decision-making and implementation of this project are done by City Hall,” he said, adding that he was unaware if any request has been made.

Sam Piseth, director of the municipal Department of Public Works and Transport, declined to comment on the project yesterday.
