As 2021 looms on the immediate horizon, a controversial plan is back on the table again. Officials from the San Mateo Public Works Department have scheduled an online discussion of a proposed traffic improvement options involving the Peninsula Avenue/Highway 101 interchange next month. The virtual event is set for Jan. 27. The interchange has been a source of serious debate for decades. Originally constructed in the late 1940s, it was razed and rebuilt to modern standards 10 years ago. But authorities were well aware that, even with the fresh construction and greatly enhanced northbound Highway 101 access (along with a more direct link to Coyote Point and other Bayfront properties), the interchange remained woefully inadequate because of a total lack of southbound access.Â
