Express Bus Service 518A is a unidirectional route variant of Express 518, connecting the residential estate of Pasir Ris to the City areas, such as Moulmein, Orchard Road, Marina Centre and Bayfront. It incorporates a express sector from Loyang Avenue to Moulmein Road via the TPE, PIE and CTE.

The route offers a quicker alternative route for passengers at Pasir Ris heading to the city, by skipping long sectors within Tampines and Bedok North, hence reducing travel time and overcrowding on the parent Express 518. Two trips are operated on weekday mornings.

Buses may ply alternative routes along the Express sector subject to traffic conditions.
