The ECP connects Changi Airport in the east through the Benjamin Sheares Bridge to the Marina Bay and Central Business District areas in the south.

After Exit 13 for Fort Road (signed 14A eastbound), the ECP curves further inland passing through the interchange with the MCE and KPE before the Benjamin Sheares Bridge which offers a beautiful view of the downtown.

The ECP then ends near the 16-kilometre mark and merges with Sheares Avenue (newly formed as part of the truncated section of the former route).

On 3 September 1970, a $35 million plan was put in place to reclaim more land off of Bedok, with the final phase starting on 7 October 1970.

On 24 May 1973, the government proceeded to build a $300 million highway across the harbour to the breakwater line outside Clifford Pier to ease peak hour congestion at the Collyer Quay area.

The 280m long bridge was to be built at a height of 30 ft above high water level to allow ample headroom for ferries to use the channel.

On 28 February 1974, the government also acquired two portions of land, for the extension of Bedok South Avenue 1 from Upper East Coast Road to the ECP.

[1] The extension of East Coast Parkway was to run from Tanjong Rhu via the Kallang River to Marina Centre.

Construction of the first phase of the East Coast Parkway from Fort Road to Marine Parade started in 1971 and was completed in December 1975.

The government had decided to further reclaim the Marina South area, linking Tanjong Rhu and Telok Ayer Basin.

[4] A decommissioned emergency highway strip was built in the long, straight section of the ECP close to Changi Airport.
