SINGAPORE - The Land Transport Authority (LTA) has awarded two more contracts under its Walk2Ride programme, which will add more than 200km of new sheltered walkways around key public transport nodes by 2018.

Both contracts, worth a total of $143.8 million, were awarded to Or Kim Peow Contractors, the LTA said in a statement on Monday.

One contract will cover 38 LRT stations in Bukit Panjang, Sengkang and Punggol, and is worth $60.9 million, while the other - worth $82.9 million - will cover 29 MRT stations in the central and southern parts of Singapore as well as Bukit Merah bus interchange.

Works are expected to commence in the fourth quarter of this year and will complete progressively by 2018.

In May last year, the LTA also handed out two contracts for the provision of sheltered walkways around 59 MRT stations in the north-eastern and north-western parts of Singapore. Works for these projects have already started.

Currently, sheltered walkways are provided from transport nodes to schools and healthcare facilities within a 200m radius. They are also built within residential estates by town councils.

Under the LTA's Walk2Ride programme, first announced in January 2013, coverage was expanded to schools, residences and public amenities within a 400m radius of all MRT stations and a 200m radius of all LRT stations and bus interchanges.
