That blocked the southbound lane--already narrowed by the construction fence for the tower-- and posed hazards for drivers and bicyclists in both directions.
As shown in the screenshot at right, northbound traffic was unimpeded, as long as the southbound traffic was paused near Pacific Street.
Otherwise, the constriction forced the southbound vehicles to move into the northbound lane.
Avoiding truck congestion was one of the justifications for the now-abandoned plan to build the entire project via modular construction, wasn't it?
And why shouldn't such incursions generate fines?
