The city is eying plans to connect Eighth and First Avenues with four pairs of crosstown bike paths, just ahead of launching an ambitious bicycle share program that will flood the street with 10,000 two-wheelers.

The streets under consideration for the lanes — which will run one-way in the same direction as traffic — are 39th and 40th, 43rd and 44th, 48th and 51st, 54th and 55th Streets.

Some of those streets already have sporadic stretches of bike lanes, but those lanes don’t connect.

Any new lanes would likely not have barriers to protect cyclists from vehicles.

It’s unclear when construction would begin, but officials have begun reaching out to the communities to gauge reactions of residents.
