Lane reductions on local roads and streets.

Prohibits, in a city with a population of at least 50,000, a governmental entity or private contractor from engaging in a project that would result in the permanent restriction or reduction of one or more travel lanes within the city as the result of the project. Provides that if a governmental entity or private contractor violates the prohibition, the state comptroller shall withhold 10% of the total amount of the distribution from the local road and street account that would have otherwise been distributed to the city during the calendar year following the calendar year in which the travel lanes became restricted or reduced. Provides that any distribution amount withheld by the state comptroller reverts to the state general fund. Exempts existing rapid transit lines from, and lists other exceptions to, the prohibition.
