Consequently, ferries going through Active Pass have to sound their whistles upon entering and leaving the passage, and must adhere to a lower speed limit while transiting through it.

On the Mainland, Highway 17 is known as the South Fraser Perimeter Road (SFPR), a component of the British Columbia Ministry of Transportation's Gateway Program.

The road then runs through the west side of Burns Bog, but avoiding the conservation area, and past the south side of the Tilbury and Sunbury industrial areas for 9.7 kilometres (6.0 mi) before it reaches the Fraser River at an interchange connecting to Highway 91 via Highway 91 Connector.

In 1978, the highway was extended and aligned along Blanshard Street through Downtown Victoria to the Inner Harbour in an effort to improve traffic flow.

The provincial government proposed to build a new expressway, the South Fraser Perimeter Road (SFPR), linking the Tsawwassen Ferry Terminal with the Trans-Canada Highway.

[8] The South Fraser Perimeter Road project was opposed by a number of groups, citing a variety of concerns.

[11] In response to the mitigation measures proposed the Environmental Stewardship Branch of Environment Canada wrote that "... the changes are not sufficient to alleviate its concerns related to the impacts of the Project on Pacific Water Shrew (PWS), hydrology, aerial deposition, and ecological integrity of Burns Bog.

"[12] On November 24, 2010 the Burns Bog Conservation Society launched a lawsuit intend to force the re-routing or cancellation of the SFPR project.

[14] The Wilderness Committee and other groups have criticized the SFPR, and the Gateway Program in general, for increasing greenhouse gas emissions.

[15] In early 2011, a protest camp organized by StopThePave.org and the Council of Canadians occupied a SFPR construction site for almost two weeks.

[18] On March 10, 2017, an announcement was made to address congestion at Highway 17 (Delta): an extension of westbound slip lane from Tilbury Connector (80th Avenue) intersection, replacement of the traffic light-controlled Highway 91 Connector with an interchange, and construction of a new interchange at River Road.

[23] As part of the Pattullo Bridge replacement project, the initial plan included a new interchange to provide direct connections to and from Highway 17 to the bridge as well as an extension of Scott Road north of King George Boulevard to directly connect with Highway 17 to divert traffic from local streets in Surrey.
