Traffic, Transit Advisories

Here are some issues you may have to deal with on the roads and rails during the rest of this week.

Westbound I-66 at Route 29, Gainesville
On Wednesday, from 7 a.m. to 2 p.m., ramp 43A southbound to Route 29 will be closed to allow the I-66 widening project to remove the steel girders of the ramp's deck. Interstate traffic will use exit 43B to northbound Route 29, then bear left on the ramp to reach southbound Route 29. This pattern will not affect traffic northbound onto Route 29.

Route 29 South, Gainesville
On Thursday, from 7 a.m. to 3 p.m., Route 29 South from Larapinta Court to Wellington Branch Drive will be closed to allow the widening project to lift and remove the structural steel beams off the old bridge over Route 29. The two Route 29 northbound lanes will be converted into a two-lane undivided highway configuration to allow one lane to function as Route 29 North and the adjacent lane to function as Route 29 South. The Route 29 Southbound traffic will cross over the median just before Larapinta Court and use the Route 29 northbound left lane. After going under and past I-66, the Route 29 Southbound traffic will cross back over to the right.

Traffic for I-66 eastbound from Route 29 southbound will make a U-turn before Route 55 and use the Route 29 northbound on-ramp to I-66 eastbound.

Beltway Bridge Repair
Route 50 eastbound at the outer loop will be closed overnight Tuesday and Wednesday. The closures are scheduled to last from 10 p.m. to 5 a.m. each night. Here's the detour: Eastbound traffic on Route 50 will go to a southbound service road paralleling the Beltway, then back to eastbound Gallows Road over I-495 to the inner loop and back to Route 50.

The closure makes room for the repair project that will fix the bridge girder damaged last year in a truck accident. That's been the reason for the ramp lane closure on the bridge. The entire repair project is scheduled to be done by May 12, VDOT says, though there's a chance it could be done sooner.

RC Parkway Trail Closed
The hiker-biker trail on the Rock Creek Parkway was shut Monday for about a month between Virginia Avenue and the P Street ramp. Watch for detour signs to guide you around the construction project and onto Georgetown streets. (This is part of the year-long reconstruction in that area scheduled to end in the spring. Drivers were real hot about this last summer and fall. I didn't hear many complaints over the winter.)

Poolesville Road Project
The Maryland State Highway Administration has begun a resurfacing and safety improvement project along Route 109 (Beallsville Road) between Route 28 (Darnestown Road) and the bridge over the Little Monocacy River. The work should be done this fall.

Watch for lane closures and lane shifts along Route 109 between 9:30 a.m. and 3:30 p.m. Mondays through Fridays. There may also be lane closures between 7 p.m. and 5 a.m. Sundays through Thursdays.

Metro Elevator Shut
The elevator at Capitol South Station will be closed for maintenance from 9:30 a.m. today till about 2 p.m. Friday.

Tysons Lane Closures
Both lanes of the Route 7 East Service Road are scheduled to closed at Gosnell Road through Friday so Washington Gas can realign its line through that area. This is part of the prep work for the Dulles Metrorail line.

Actually, Bob, if you want to be technically correct, Washington Gas is moving the line for the rebuilding of Route 7, not just for metro. I believe that Route 7 is going to be reconstructed (only about 20 years overdue, but that's another story) regardless of the metro.

Last year, Rock Creek Parkway lane closures were so bad because they were taking over half the capacity away at the biggest bottleneck (the Virginia Avenue signal) at all times...including rush hours. Now, the lane closures seem to be limited to north of M Street, meaning the Virginia Avenue signal is still operating at full capacity. Also, lane closures are limited to off-peak hours, so there are no really bad residual delays from rush hour. The dreaded southbound right lane closure was in effect today, but only about a 2 - 3 minute delay, whereas last fall delays were about 15 - 20 minutes.

they should close all the roads and just bike to work but I dont know how that would work because bikers are above the law and would just run into each other in intersections because no one has the basic human decency to stop

Bob, could you put a specific date in your advisories? Instead of just "will be closed this Thursday" could you say "will be closed Thursday, March 13" -- I read your column online and the date when it is posted doesn't appear on the blog prominently. Thanks.
