Left-turn lanes are a highly effective
method for improving traffic flow and reducing accidents at
Each year, left-turn lane
construction is considered at many intersection locations
of the City’s more than 1,400 miles of arterial streets
and main thoroughfares. There are more than 11,000 left-turn
lanes and nearly 400 miles of two-way left-turn lanes in Los
A conventional left-turn “pocket”
lane is provided at many important, high-traffic intersections.
A two-way left-turn lane is use to accommodate left turns

LADOT considers whether large development
projects are nearby before reducing street parking. A large
amount of curbside parking is not usually needed if these
projects do not exist.
In other situations,

order to accommodate left-turn pockets or two-way left-turn
