Ah, the weekend: Here's a list of highways and byways to avoid

With Hwy. 100 closed in St. Louis Park and a partial closing of 1-35E, transit might not be a bad way to get around this weekend. But for those traveling by car, here is what you'll need to know to get around.

Hwy. 100 in St. Louis Park

Work on the Canadian Pacific Railway bridge means a full shutdown of Hwy. 100 between I-394 and Crosstown Hwy. 62 until 5 a.m. Monday.

During the closure, traffic will be detoured via I-394, Hwy. 169 and the Crosstown. What's happening? Trucks will deliver steel for the new bridge that's part of a remake of Hwy. 100, which includes adding an auxiliary lane, reconstructing the Minnetonka Boulevard and Hwy. 7 bridges and ramps, and building noise walls.

I-35E in St. Paul

Motorists saw the southbound lanes shrink last week around Maryland Avenue. This weekend, the two southbound lanes will remain open, but northbound will be closed from I-94 up to Cayuga Street until 5 a.m. Monday.

I-494 in Plymouth

Several ramp closures also are in place at Carlson Parkway, I-394 and Hwy. 12.

Hwy. 5/West 7th Street

The redecking of the Mississippi River bridge has wrought a nightmare for drivers trying to get to and from the MSP Airport. The road is down to a single lane in both directions between Fort Snelling (Hwy. 55) to Shepard Road. Additionally, eastbound Hwy. 5 ramps to Edgcumbe Road, Shepard Road and Mississippi River Boulevard are closed through September.

Also look for single-lane action near Maynard Drive as crews fix a water main.

Hwy. 10 in Ramsey

Kellogg Blvd. in St. Paul

Kellogg is closed between Market Street and Wabasha Street until November, as are the southbound lanes on the Wabasha Bridge, and the northbound lanes of the Exchange Street viaduct.

Motorists are directed to use 7th Street and Robert Street.

Minnehaha Av., Mpls.

Street reconstruction will greet people headed to Minnehaha Park Saturday for Twin Cities Tour de Cure, a fundraiser of the American Diabetes Association.

The intersections at 46th Street and 44th Street will remain open.

Minneapolis Marathon

Sunday's full and half marathon take place primarily along the Mississippi River and on some streets on the city's north side. Neighborhood detours will be in place, along with restrictions on reaching places such as North Memorial Medical, Theodore Wirth Golf Course and residences near the Stone Arch Bridge. Closures will be in place from 6:30 a.m. to 3 p.m.

I-94 in St. Michael

Motorists might encounter delays because of freeway repaving between Hwy. 241 in St. Michael and County Road 18 near Monticello. Nightly lane closures will be in place from 7 p.m. to 5:30 a.m. while crews resurface 9 miles of road. Also watch for a lane shift near the Crow River Bridge.

Hwy. 169 between Hwy. 21 and Hwy. 282 is down to a single lane and a 45-mph speed limit through late October.
