Drivers commuting to work on the 5 freeway close Atwater Village may have seen a goliath white pillar standing out of the Los Angeles River.

That enormous white structure is a piece of an extension that, when complete, will interface people on foot, cyclists, and equestrians going between Atwater Village and Griffith Park. Development on the North Atwater Bridge started in the spring of 2018, and now the extension’s bigger pieces are beginning to emerge in the waterway bed.

Shirley Lau, a structural designer with the city’s building authority, says the extension’s “superstructure” will be up before the year’s over. That coordinates with prior projections that pegged the extension being finished this fall.

While development is in progress on the North Atwater Bridge, a part of the bicycle way nearest to the task is shut and will stay covered until December.

The LA River is clamoring with extension building movement. In Cypress Park, work started a month ago on a splendid orange extension that will interface the bicycle way on the Elysian Valley side of the waterway to Cypress Park and an arranged park at Taylor Yard.

North of the North Atwater Bridge, another scaffold is wanted to connect Glendale and Griffith Park.

Closer to Downtown, the monstrous Sixth Street Viaduct is advancing toward its evaluated 2020 finishing date. The $482-million, Michael Maltzan-planned venture will cross the 101 turnpike and the stream, associating Boyle Heights and the Arts District.
