The Calera Parkway Project proposed to widen Highway 1 to six lanes between Fassler and Reina del Mar in an effort to ease peak-hour congestion.  During years of local controversy, twice as many Pacificans spoke against the widening at every opportunity.  The project EIR is tied up in the courts.  Then the 2016 elections brought a shift in City Council majority on this issue.

In March 2017 the Pacifica City Council adopted an ordinance that prohibits any formal Council action to support or approve the construction of additional through lanes along Highway 1 without first obtaining a majority voter approval of the Pacifica electorate.

On June 12 the City Council approved a letter asking Caltrans to abandon the proposed widening and remove it from further consideration.  The Council believes that through a combination of alternatives, excluding widening, an environmentally sustainable solution to the congestion can be achieved.
