After its successor was opened to traffic, the old bridge was demolished by reverse construction, a process which took three years to complete.

[20] In 2001, an eastbound HOV lane was added by moving the centre divider and by cantilevering the bridge deck outwards in conjunction with a seismic upgrade.

[21] On January 31, 2006, the British Columbia Ministry of Transportation introduced the Gateway Program as a means to address growing congestion.

It only takes a little undetected fatigue crack to grow for 10 years and then a member eventually just snaps through one cold morning when the wrong size truck rolls over it”.

[23][24] Opponents of the expansion included local environmental groups, urban planners,[25] and Washington state's Sightline Institute.

The Livable Region Coalition urged the Minister of Transportation, Kevin Falcon, to consider rapid transit lines and improved bus routes instead of building the new bridge.

[29] The Port Mann / Highway 1 project added another HOV lane along with cycling and pedestrian access.

[38] On February 10, 2012, during construction of the replacement bridge, an overhead gantry crane collapsed, causing a 90-tonne concrete box-girder segment to drop into the water below.

[40] ICBC, the vehicle insurance entity in British Columbia, reported 60 separate claims of ice damage during the incident.

[41] The Government installed collars on the cables that are manually released when conditions for ice accumulation are expected.

"[43] During December, the bridge was closed due to the threat of falling snow off of the cables and possible icy conditions.

[44] In order to recover construction and operating costs, the bridge was electronically tolled when originally built.

[45] Through increased prices and greater traffic, Transportation Investment Corporation (TI Corp), the public Crown corporation responsible for toll operations on the Port Mann Bridge, forecast its revenue would grow by 85% between fiscal years 2014 and 2017.

[46] These fees were assessed using radio-frequency identification (RFID) decals or licence plate photos.

[51] Users who opted for this method received a decal with an embedded RFID to place on their vehicle's windshield or headlight and avoid paying a processing fee.

Debt service was transferred to the province of British Columbia at a cost of $135 million per year.
