As the road construction season heats up, drivers will encounter fresh hells. But some projects across the Washington region are scheduled to end. Here's a look ahead at some of the most significant work, including some with changes this week.


1. The Intercounty Connector under construction in Montgomery and Prince George's counties will account for the year's most prominent developments.

Connector, part 1: The first segment of the six-lane toll road, the western part between Interstate 370 and Georgia Avenue, is scheduled to open late this year.

New traffic pattern: This week, commuters should be alert for a new traffic pattern at the Shady Grove Road/I-370 interchange resulting from connector construction. Drivers heading west on Shady Grove Road toward westbound I-370 will make a left at a new traffic signal. They will merge with the eastbound Shady Grove Road drivers heading for I-370 on a new ramp.

Interchange construction: Construction will continue on the connector interchanges at Route 29 and I-95. Watch for lane shifts and temporary lane closings.

2. Rockville Pike interchange: The new junction at Montrose Parkway, Rockville Pike and Randolph Road began construction in summer 2008 and has opened in segments. It is scheduled to be finished this fall. During spring and summer, crews will work on sidewalks, excavate for a new ramp from Montrose Parkway to the northbound pike and build a park-and-ride lot on Montrose Road.

3. Capital Beltway bridge: Reconstruction of the Route 201 (Kenilworth Avenue) bridge over the Beltway is getting underway, and completion is scheduled for summer 2011. Watch for temporary lane shifts and lane and shoulder closings on Kenilworth and the Beltway. At times, the shoulder on Kenilworth will be used as a through lane. On the Beltway, the shoulders will be closed for the length of the project, and there will be some lane closures at off-peak hours.

4. Route 301 bridge: Rehabilitation of the bridge deck over Route 214 (Central Avenue) began last summer and is scheduled to be done this summer. Coming work includes installation of the new deck on the westbound side.


5. 14th Street bridge: Later this spring, the rehabilitation that began last spring is scheduled to move out of its first phase, which closed the right-hand lane on the northbound bridge. The new phase will begin a progression of lane closings, although four will always be available during rush hours.

6. Chain Bridge: The rehabilitation project, which also began last spring, was scheduled for completion in January. Winter weather had a severe impact on the schedule. Restoration of the bridge's third lane, taken away to create a work zone for the project, is now set for May 31.

7. 11th Street bridge: Work is underway on bridge piers in the Anacostia River and on the approaches to the replacement bridges to be built between the two old spans. Most of the current construction is away from the existing lanes. Considering the size of this project, the traffic impact this year should not be significant.
