Bartley Road is split into three sections with the dividers at Upper Paya Lebar Road and Kaki Bukit Avenue 4. The three sections are the original Bartley Road, Paya Lebar Viaduct, and Bartley Road East (Kaki Bukit Viaduct).
Bartley Road With a distance of 1.5km, the original stretch of Bartley Road extending from Upper Serangoon Road to Upper Paya Lebar Road, was also a part of the
Outer Ring Road System.
Paya Lebar Viaduct With a distance of 2.2km, the Paya Lebar Viaduct section extending from Upper Paya Lebar Road to Airport Road, has a 1.3km four-lane
carriageway long viaduct above the road. The viaduct also has a slip road at the Hougang Avenue 3 junction. The contract was initially awarded to L&M Prestressing and was originally scheduled for completion by end-2004. However, work slowed in 2002 because L&M encountered financial problems.L&M then promised that the viaduct would be completed by 2006. As soon as the 2006 extended dateline was not met, LTA awarded Hock Lian Seng in 2006 to finish the delayed project and was completed in January 2010 after a delay of five years.
Bartley Road East With a distance of 2.1km, Bartley Road East or Kaki Bukit Viaduct, is a viaduct starting from Kaki Bukit Avenue 4 and ends at the junction of Tampines Avenue 10 and Bedok Reservoir Road. It was opened to traffic on 30 December 2003. ==Bartley Road Extension Project==
