The Land Transport Authority (LTA) has called tenders to install lifts at 17 existing pedestrian overhead bridges in areas such as Boon Lay Way and Serangoon Central.

In January, Transport Minister Lui Tuck Yew had announced that the LTA will install lifts at 40 overhead bridges islandwide. The 17 are the first batch of 40 to be retrofitted.

In a statement, the LTA said the installation of lifts "is part of efforts to further enhance accessibility to our transport infrastructure, especially for the less mobile". Construction will begin early next year and the lifts will be progressively completed from 2016.

The LTA will announce the locations of the remaining overhead bridges by early next year.
