SINGAPORE - Land Transport Authority chief executive Chew Hock Yong, 49, will become second permanent secretary, Ministry of National Development, from Oct 1.

He will oversee the Municipal Services Office announced by the Prime Minister at the National Day Rally recently, and will also be closely involved in the MND's strategic and land planning, and housing portfolios.

During his tenure at the LTA, several significant infrastructural projects and policy changes were implemented. These include the commissioning of the Circle Line, Downtown Line 1 and Marina Coastal Expressway. Under his leadership, LTA also introduced the Bus Service Enhancement Programme, the Bus Service Reliability Framework and the Taxi Availability Framework. He also helped in formulating and introducing the new bus contracting framework - which paves the way for more direct government subsidies for public bus services.
