There’s no rain in the Capital Weather Gang forecast till Friday, but travelers face a very hot week, with temperatures in the 90s Wednesday through Friday. Let me know about any hot Metrorail cars you encounter, but let Metro know first by contacting the train operator over the intercom or calling Metro’s customer service number, 202-637-1328.

With no rain in the immediate forecast, drivers are likely to encounter a full schedule of road work on many major routes. You’ll see some of the highlights here.

14th Street Bridge

Lane closings starting at 10 p.m. Tuesday will allow the relocation of the 14th Street Bridge work zone in time for the Wednesday morning rush. This will be the final phase of the two-year-old project to reconstruct the surface on the northbound span. It’s scheduled to be done in the fall, but I hope the rapid pace of the recent work will lead to an earlier wrap-up.

The new phase starts Wednesday morning, putting the construction island in the right center lane on the north half of the bridge, with three lanes routed to the left and one lane to the right. The placement should be less confusing than the current one for drivers coming up Interstate 395 from Virginia into the District.

But drivers coming onto the bridge from the northbound George Washington Parkway will need to be very careful. They will have only a short time to move left if they’re trying to reach lanes bound for 14th Street in downtown Washington. If traffic congestion won’t allow that merge, just stay where you are and take the right-side exit for 12th Street.

I-66 meetings this week

Here’s a look at the future. The Virginia Department of Transportation will hold two citizen information meetings, sponsored jointly with the Virginia Department of Rail and Public Transportation, to discuss the state study on various ways to improve travel in the Interstate 66 corridor from the Beltway west to Route 15 in Prince William County, a distance of about 25 miles.

VDOT says the study will identify transportation needs within the corridor and evaluate the impact of proposed improvements. The study is scheduled to be done in late 2012.

The first meeting is scheduled for 5 to 8 p.m. Wednesday at the Four Points by Sheraton, 10800 Vandor Lane, Manassas. The second will be Thursday, same time, at the Virginia Department of Transportation’s Northern Virginia District Office, 4975 Alliance Dr., Fairfax.

Beltway lane closings in Tysons

The Dulles Metrorail project has resumed the overnight lane closings on the Capital Beltway at Route 123, where workers are building the bridges that will carry the tracks over Beltway.

The two right lanes on the inner loop are scheduled to close Monday from 11 p.m. to 5 a.m. Crews will close three lanes from 11 p.m. to 5 a.m. Tuesday through Thursday nights and from 10:30 p.m. Friday to 7 a.m. Saturday.

Beltway traffic will be allowed to pass through the interchange, but drivers should expect delays. The inner loop lanes will begin to taper near Route 7 (Leesburg Pike).

All ramps to and from Route 123 will remain open, except for the ramp from southbound Route 123 to the Beltway’s outer loop, which will be closed in the overnight work hours starting Thursday.

HOT lanes closings

These are the nightly lane closings scheduled this week on the High Occupancy Toll lanes project in Virginia.

Capital Beltway inner loop at I-395: Beginning at 9 p.m. each night through Saturday, one lane will close on I-395, progressing to a full closing of the inner loop after 11 p.m. Motorists will be detoured to I-395 north to Exit 2, Edsall Road, follow signage to I-395 south, and take Exit 1D to I-495 north. All lanes will reopen by 5 a.m. weekdays and by 7 a.m. Saturday and 9 a.m.Sunday. This closing allows crews to continue bridge work.

Dulles Toll Road (Route 267) east to the Beltway: Beginning at 9 p.m. each night through Saturday, one lane will close on Route 267 at the Beltway, progressing to a full eastbound closure after 11 p.m. Motorists will be directed to I-495 south, to Exit 46B, Route 123 north, follow the signage to turn left onto I-495 north. All exit ramp lanes will reopen by 5 a.m. weekdays, 7 a.m. Saturday and 9 a.m. Sunday. This closing allows workers to install steel bridge beams.

I-66 east at the Beltway: Tuesday through Saturday nights starting at 9:30, one lane will close on I-66 east at the Beltway, progressing to a full I-66 east closure after 11 p.m. Motorists will be detoured to I-495 south to Exit 52B, Little River Turnpike east (Route 236), follow signage to I-495 north, back to Exit 49B, I-66 east. This closing allows crews to complete bridge demolition.

Fairfax County Parkway

A new phase is underway in the reconstruction of the Fairfax County Parkway’s busy junction with Fair Lakes Parkway. Drivers won’t be able to go directly between Fairfax County Parkway and North Lake Drive. This is a permanent closing, part of the plan for the new interchange, which will widen the parkway in that area.

Once sound walls are placed across North Lake Drive, a cul de sac will be built. Residents in the Villages of Fair Lakes will use Route 50, to the north, for access to their homes.

The Virginia Department of Transportation’s $69.5 million interchange construction project, assisted by Fairfax County and a big infusion of money from the federal stimulus program, is rebuilding one of the oldest and most congested stretches of the county parkway. The project will open in phases, but all the work, including the final paving, should be done by October 2013, VDOT said.

University Boulevard paving

Watch for single lane closings from 9 a.m. to 3 p.m. weekdays on University Boulevard between Arcola Avenue and Route 29 (Colesville Road) in Silver Spring for a paving project.

Beltway/Telegraph Road

This weekend, the outer loop THRU/LOCAL lane split is scheduled to shift east of its current location to make room for work on a new portion of the THRU lanes.

About 9 p.m. Friday, one THRU lane will be closed, leaving two LOCAL lanes open. Then starting at 9 p.m. Saturday, one THRU lane and one LOCAL lane will be closed, leaving only one LOCAL lane open to traffic. All lanes will reopen at 9 a.m. Sunday.
