Italian-Thai Development has secured the contract to construct the 16.2-kilometer Chatuchak-Lam Luk Ka extension of the Chalongrach Expressway at an estimated cost of 24 billion baht, with completion projected for 2027.

Expressway Extension Sets Timeline for Coordination

The project links directly to existing routes serving Chatuchak district. District officials must now decide how local traffic patterns will adjust once the new section opens and how feeder roads will connect to the expressway without creating bottlenecks at key intersections.

Bang Sue Grand Station Anchors Rail Network

Bang Sue Grand Station in Chatuchak district operates as Thailand’s largest railway station in Southeast Asia, covering 171,000 square metres with 26 platforms. The station already functions as the central hub for multiple rail lines, requiring planners to align future expressway access points with passenger flows at this location.

Power Infrastructure Supports Expanded Operations

A high-voltage power station built in Chatuchak supplies electricity to Bang Sue Grand Station and the SRT Red Lines through 230 kV transmission connections. Decisions ahead include determining capacity margins for additional rail services and ensuring maintenance schedules do not disrupt station operations.

Park Facility Upgrades Address Daily Use

The Bangkok Metropolitan Administration is upgrading public restrooms at Chatuchak Park, with one facility undergoing full reconstruction and another receiving modernization work. These improvements form part of wider public infrastructure work and will need integration with visitor access routes tied to the nearby station and expressway.

Authorities will next determine how the completed expressway, expanded rail services and upgraded park facilities operate together. Key choices involve sequencing construction phases, allocating maintenance responsibilities among agencies and establishing clear signage and access protocols for residents and travellers using multiple modes in the district.
