Weekend Road and Rail: I-66 stoppages, Beltway bridge work; Metro has two shutdowns and single tracking

Since spring has almost sprung, at least for this weekend anyway, the work planned for Interstate 66 in Fairfax and Gainesville will likely continue, which is the same for the Capital Beltway and D.C. Route 295/Interstate 295.

Metro has another planned shutdown on the Red Line to go along with the Blue Line’s continued closure. Riders can expect single-tracking on the Yellow Line.



This weekend, the weather is expected to be welcoming amidst the perpetual work zones that take up many lanes and ramps on I-66, as various interchanges and bridges transform I-66 outside the Beltway project.

All week long, travelers through this interchange have seen stops on I-66 and the U.S. Route 50 interchange overnight, which is expected to continue into this weekend. The bridge overhaul at this interchange sees I-66 westbound to Route 50 reduced to a single lane of travel on the approach from the Waples Mill Road overpass, with random stops of up to 10 minutes at a time. All traffic at the point is detoured off of the interstate toward westbound Route 50.

This work also closes the ramp from Route 50 westbound to I-66 west with Route 50 being reduced to a single lane and periodic stops up to 20 minutes.

This bridge beam installation project generally occurs nightly, weather permitting, between the hours of 9 p.m. to 5 a.m. with the work into Saturday morning possibly extending to 9 a.m. The full stops are generally scheduled between midnight and 4 a.m.

There has also been continued work this week on I-66 westbound near the Prince William Parkway (state Route 234 Bypass), which includes lane reduction and overnight stops. With the transformation project, it is VDOT’s plan to have Express Lanes run between the Beltway and Gainesville, which means expanding transit and carpool use on the I-66 corridor by adding a new Park and Ride lot in Gainesville at University Boulevard and U.S. Route 29 (Lee Highway). Crews have been working here nightly at the University Boulevard bridge, which spans I-66 just to the east of Route 29 in Gainesville.

This work is scheduled nightly, through midday Saturday, with travel being reduced to a single lane westbound on I-66 between the Prince William Parkway and Route 29 (Gainesville). Also, only one lane is open on University Boulevard starting on or about 6 p.m. nightly with two-way, alternating travel controlled by flaggers.

There is a new project taking place overnight this weekend for the transformations that includes the ramp from Interstate 495 Capital Beltway toward westbound I-66. In the overnight hours, both Saturday and Sunday, crews will close the ramp from the Outer Loop (I-495 south) to implement a lane shift.

The work and closure will be each night with traffic being detoured farther south to Route 50 for a U-turn. On Saturday night the work is from 11 p.m. to 7 a.m., with Sunday night from 10 p.m. to 4 a.m.

As this ramp reopens Monday morning, there will once again be two lanes available for travel, which is an upgrade since there’s only been one lane open since January.

As these work zones are everchanging between the Beltway and Gainesville, and with weather disrupting many planned events, a lot of changes can happen during off-peak hours.

In Frederick, this week saw a new off-peak project kick off state Md. Route 180 (Jefferson Pike) between U.S. Route 340 and Md. Route 17 (Burkittsville Road) roundabout. This includes highway maintenance with roadway patching causing single lane closures 8 a.m. to 4 p.m. daily, with Saturday work possible on a two mile stretch of state Route 180. According to the Maryland State Highway Administration (MDOT SHA) this project is projected to be completed by May.

There also continues to be the nightly work on Interstate 270 at the exit ramp for Md. Route 85 (Buckeystown Pike). With pipe installation, crews close the ramps to I-270 to northbound Md. 85 nightly Sunday through Friday. And on I-270 southbound between Md. Route 121 (Clarksburg Road) and Md. Route 109 (Old Hundred Road) there also continues to be single to double, off peak, lane closures.

On Interstate 70, there are two bridge repair projects taking place over the Patapsco River and the CSX Rail Line bridge. This work is scheduled daily between 9 a.m. and 3 p.m., plus overnight between Sunday and Thursday, weather permitting.

MDOT SHA also has a new resurfacing project in Prince George’s County on Md. Route 5 (Branch Ave) between the District line and Curtis Drive. This project is expected to intermittently close lanes on off-peak hours daily in both directions, including weekends between 5 a.m. and 10 p.m., and overnight.

The work on the Beltway in Montgomery County between Georgia and Connecticut avenues will experience off peak bridge rehabilitation with daily lane closures, overnight triple-lane closures and full stops – which will likely continue through late fall.

That’s the same scenario for the Beltway’s bridge replacement project at the Suitland Parkway in Prince George’s County. Crews there continue to work during off-peak times between Md. Route 4 (Pennsylvania Avenue) and the Allentown Road/Joint Base Andrews exits. There are daily single-to-multiple lane closures permitted both midday and during the overnight hours.

There is an upcoming traffic disruption starting Monday that will impact two Bethesda roads in a new project expected to last through April.

These off-peak daily lane closures can be expected on Sangamore Road between Massachusetts Avenue and Walhonding Road for pipe installation. Massachusetts Avenue at Sangamore Road is expected to be detoured for the duration.

Also in a look ahead to next week, work continues on I-895 Harbor Tunnel Throughway. Beginning next week, the Southbound Tunnel is scheduled to be closed at 8:30 p.m. nightly Monday through Thursday for scheduled work. Two-way operations will be in the northbound tunnel. Re-opening is scheduled to take place at 4:30 a.m. the following morning.

Firth Sterling Avenue will also be closed during this time between South Capitol Street southeast and St. Elizabeth’s Avenue southeast with a detour posted.

Travel on northbound South Capitol Street will be closed and rerouted around Nationals Park again this weekend between 5 a.m. and 8 p.m. both Saturday and Sunday.

And DDOT’s sign replacement project has been occurring nightly with lane closures possible on Interstate 395 and I-695, scheduled into Saturday morning. Motorists overnights could find temporary lanes, ramps, and shoulder closures, weather permitting.
