Two major streets in downtown Minneapolis are changing from one-way streets to two-way streets on Sunday, one day later than originally announced.

The wet streets overnight prevented crews from painting stripes on the pavement, which caused the delay.

Minneapolis Public Works crews plan to begin the conversion Sunday at 11 a.m., barring further weather delay.

The goal of the $3 million conversion is to allow downtown visitors to drive more directly to their destinations.

The details:

• On Hennepin, three northbound through lanes will be replaced with one through lane in each direction, designated left-turn lanes, and combined bike-bus-right-turn lanes.

• On 1st Avenue, bike lanes will run along the curbs, with off-peak parking allowed next to the bike lane -- 6 feet from the curb. The idea is that parked cars will serve as a buffer between moving traffic and the bike lane.

• "Bike boxes" painted at intersections will require cars to stay back from crosswalks about 10 feet to give left-turning bicycles a place to wait in front of motor-vehicle traffic.

Extra traffic control officers are slated to be on hand tonight -- prime bar-hopping time in the Warehouse District -- as well as during the morning commute Monday.
