Planning Board rejects Montgomery Parks recommendation on Capital Crescent Trail Crossing of Little Falls Parkway

At the Montgomery County Planning Board meeting on June 13, 2019, Montgomery Parks presented their recommendation reported in the 6/7/2019 post immediately below. Unusually, the Planning Board rejected the Parks staff recommendation. They voted to return Little Falls Parkway to its original configuration of 2 lanes each way, and to move the CCT crossing over to the traffic light at Arlington Rd. This was by a 4-1 vote, with Chair Casey Anderson the dissenting vote. This change will require significant construction work, even though it leaves the roadways unchanged, so the crossing will stay as it is for at least months, with Little Falls Parkway 1 lane each way.

Here is the video recording of this Planning Board meeting:

CCCT had recommended an approach much like what the Planning Board chose, but with the addition of re-configuring the Arlington Rd/Little Falls Parkway/Glenbrook Rd intersection so that Arlington - Little Falls is the thru street, with Glenbrook intersecting as a T, replacing how Arlington Rd currently intersects as a T. Here are the comments CCCT submitted to Montgomery Parks with this recommendation.


Montgomery Parks report on safety improvements project at the Capital Crescent Trail Crossing of Little Falls Parkway

The report recommends Alternative A, which "converts the existing at-grade crossing to a raised crosswalk and maintains the reduction in vehicle lanes to eliminate the multiple-lane threat and reduce vehicle speeds." The project will be presented to the Montgomery County Planning Board on June 13, 2019.

Completed - Removal of Vegetation at Potomac Aqueduct starting on 11/27 affects the trail

The National Park Service alerted us at 7 am on 11/27/2018, saying:

I apologize for the short notice. NPS will be removing vegetation from the Potomac Aqueduct today starting at 9:00 AM. It looks like the job of removing all vegetation from the faces of the Aqueduct will continue on throughout the week. Maintenance will be using a boom truck in order to remove the Ivy from the western face of the structure and any other hard to reach areas. NPS will have volunteer flaggers directing pedestrians and bicyclists through the work area. Barricades will be placed around the boom truck and signage will be placed at the trail head. Bicyclers are asked to dismount there bikes when in the work zone.

The Potomac Aqueduct is at the Georgetown end of the trail, over the gate between the trail and Water St.

Completed - Trail closure/detour for repaving at River Road Plaza, Friday October 12, 9am - 3pm

As construction of River Road Plaza nears completion, the Trail will be repaved in the Plaza area. This will take about 6 hours, during which the Trail will be blocked off from the south end of the bridge over River Road to the north (uphill) end of the construction zone for the Plaza. On 10/11, the Montgomery Parks website says that repaving will be done from 9 am to 3 pm on Friday October 12.

See the Montgomery Parks CCT page for their notifications on this paving:

During the closure, Trail users going south (downhill) will need to leave the Trail where the Plaza starts, by turning west towards Security Storage. Trail users going north (uphill) will need to leave the Trail just before the bridge. A detour will be marked, using a side path south of River Road, using the Security Storage driveway north of River Road, and crossing River Road at grade. Watch for flagmen and police directing traffic during this trail closure.

Trail is no longer detoured at Foundry Branch

The District of Columbia Water and Sewer Authority (DC Water) had been working since August 2017 on repairs to a junction box adjacent to the Capital Crescent Trail (CCT) at Foundry Branch, as part of their Upper Potomac Interceptor (UPI) project. This required a detour in the CCT, almost 1/2 mile above the Georgetown end. That repair work was completed in July 2018, and the detour is now gone.

Design of Proposed Capital Crescent Trail Tunnel in Downtown Bethesda Moves Ahead

The trail won't fit into the existing tunnel with the Purple Line, so a separate new tunnel under Wisconsin Ave is needed. This article describes 3 design options that the county Department of Transportation is considering for the eastern end of the tunnel.

Update on Capital Crescent Trail Detour due to sewer repairs at Foundry Branch - detour stays until July 2018

The District of Columbia Water and Sewer Authority (DC Water) has been working for some time on the Upper Potomac Interceptor (UPI), part of which involves repairs to a junction box adjacent to the Capital Crescent Trail (CCT) at Foundry Branch, to prepare it for re-activation. This required a detour in the CCT, described in the 8/1/2017 news item on this page. This repair work was originally projected to be completed in September 2017, but it has been delayed several times due to unforeseen circumstances, so the detour remains, probably through July 2018.

The current schedule has the repair work on the junction box adjacent to the trail starting in mid-April and taking approximately 3 weeks. Before, after, and especially during this repair work, there may be increased impact on the trail, such as for equipment access and bypass sewage pumping.

When the repairs are completed, the sewage will be directed into the new/relined Upper Potomac Interceptor and hopefully this will eliminate the type of sewage spills that occurred along the Capital Crescent Trail in 2014. DC Water will then begin to demobilize and once all the equipment is removed, they will remove the CCT detour. This should occur in July and they should be completely done in the area by August 2018 if all goes as planned.

Long term CCT closure east of Bethesda, for Purple Line construction

The Purple Line Transit Partners announced on 8/29/2017 that to construct the Purple Line Project, the trail east of Bethesda will close on Tuesday, September 5, 2017 for four to five years. This is the mainly unpaved trail between Woodmont Avenue in Bethesda and Talbot Avenue in Silver Spring, also called the GeorgeTown Branch Trail. It will re-open, predicted in 2022, as a grade-separated paved trail next to the Purple Line, extended into downtown Silver Spring.

Capital Crescent Trail Detour due to Repairs to Upper Potomac Interceptor at Foundry Branch

Washington, DC - The District of Columbia Water and Sewer Authority (DC Water) is working on the Upper Potomac Interceptor (UPI) adjacent to the Capital Crescent Trail (CCT) to prepare it for re-activation.  Work so far has included the installation of a liner and repairs to manholes.  In August 2017, DC Water will start to work on the junction box located at the Foundry Branch Tunnel.  In order to perform this work, users of the CCT will be detoured onto a parallel trail around the construction area.  This detour involves wooden ramps and sharp turns. The ramps will be coated to increase traction but may be slippery when wet. All cyclists are asked to slow down and use caution when traveling in this area. The detour will be in effect the week of July 31 and is expected to last 6-8 weeks.

Additionally, construction involves the use of heavy equipment and vehicles that travel on the CCT.  Closures of the CCT will be minimized but will occur from time to time to allow movement of equipment.  CCT users are also encouraged to use the C&O Canal Towpath to avoid this area.

The work is necessary to bring the UPI back into service and help prevent sewage spills during heavy rain events.  Construction should be completed in September 2017.


New Traffic Pattern at Trail crossing with Little Falls Parkway

Look for a new traffic pattern to improve safety at the intersection of Little Falls Parkway and the Capital Crescent Trail.  Work will start late December 2016 to improve safety at the trail crossing.  Little Falls Parkway will narrow from two lanes to one each way in the vicinity of the Capital Crescent Trail intersection.  The speed limit will be reduced from 35 mph to 25 mph.  Additional signs alerting motorists of pedestrians and bicyclists will also be installed.

CCT: TRAIL DETOUR in Downtown Bethesda! MONDAY May 26, 2015 for about 2 weeks

Please note that beginning Tuesday, May 26, 2015 the Capital Crescent Trail will begin to be detoured at Lot 31, between Bethesda Avenue and The Bethesda Rest plaza, to allow for the improvements to the (trail) CCT adjacent to the Lot 31 construction site to be constructed. The detour will last approximately 2 weeks, according to the developer.

The CCT trail will be detoured to the southern path of Lot 31 to Woodmont Avenue. Pedestrians will then utilize the sidewalks on Woodmont to continue on the trail or to reach Bethesda Avenue. Bikes will utilize the bike lanes on the roadway. To travel north bikers should utilize the mid-block crossing to reach the bike lane, traveling south bikes should cross at Bethesda/Woodmont to reach the southbound bike lane. (Variable message) VMS signs and directional signs will be placed directing the CCT detour. Please note: all access to the public parking garages will remain open.

In addition, the NW corner of Woodmont / Bethesda intersection will also undergo modifications at this time. Pedestrians will still be able to cross at this intersection, but should with caution. Signs will be set up for this improvement area also.

Thank you for your patience,

Coalition for the Capital Crescent Trail Management
