The Capital Crescent Trail's Reopening Keeps Moving. Here's What Bethesda Actually Gets When It Does

Check the Coalition for the Capital Crescent Trail's own website today and you'll find the trail described as closed between Bethesda and Silver Spring, with a reopening penciled in for "tentatively" fall 2026. That single word carries almost a decade of history. If you've lived in Bethesda through any part of this closure, you already know not to circle a date on the calendar. The trail has been closed long enough that a kid born the year it shut down is now finishing middle school. What's less understood, even among people who've been detouring around this project for nine years, is what the reopened trail will and won't include. The delays have been well covered. The part that changed quietly, buried in county budget votes rather than press releases, hasn't been.

Nine years of almost

The Capital Crescent Trail east of downtown Bethesda closed in September 2017 to make way for Purple Line construction on the old Georgetown Branch right of way. Before the closure, that stretch was a crushed stone path that crossed Rock Creek on a trestle, ran through Chevy Chase, and entered Bethesda through the 800 foot Air Rights Tunnel. None of that exists in its old form anymore. What exists instead is a construction corridor that has produced a remarkable string of official completion dates, almost none of which held.

Here's how the estimate has moved, in the officials' own words at each point:

Follow that sequence and you land somewhere strange. In 2024, the state proudly announced the trail would beat the Purple Line's own opening by more than a year. Two revisions later, the trail's newest estimate has drifted back to roughly where the original 2022 timeline had it tied to full rail service in the first place. Nine years of closure, and the working target has essentially returned to its starting point.

What's already finished

Not everything has stalled. Montgomery County built the Capital Crescent Surface Trail, a set of protected bike lanes running from the existing trailhead on Bethesda Avenue across Wisconsin Avenue, with Phase I completed around the end of 2021. That crossing already exists and already functions, at street level, alongside car traffic.

Farther east, the first genuinely new piece of trail opened on May 24, 2024, as part of the new Talbot Avenue Bridge near the Silver Spring end. It's a short stretch, roughly 670 feet including a path on the west side of the tracks and a wide sidewalk across the bridge, but it was the first tangible sign that construction was producing usable trail rather than just detour signage.

And the part most residents never think about because it never closed: the paved seven mile stretch from Georgetown into downtown Bethesda, through the Dalecarlia Tunnel, past the site of the Civil War era Fort Sumner, has stayed open and unaffected by any of this the entire time. If your daily walk or ride starts in Bethesda and heads toward the District, none of the Purple Line saga has touched you.

The tunnel that isn't coming back

Here's the part that changes what "reopening" actually means. The original vision for the rebuilt trail included a dedicated tunnel under Wisconsin Avenue, separating trail traffic from one of downtown Bethesda's busiest intersections. That tunnel's price climbed from an estimated $55 million to $82 million, and Montgomery County Executive Marc Elrich left it out of the county's capital budgets in 2020, 2022, and 2024. When the County Council considered restoring the funding in 2024, it didn't have the votes.

Compare that to what the county did fund: trail construction itself carries a projected cost of $64.3 million, which MCDOT has pointed out is about $18 million less than the tunnel alone would have cost. That's not a rounding error. It's the difference between a grade-separated crossing and a street level one at a location where trail volume has historically numbered over a million users a year.

The practical result is that when this segment finally reopens, whether that's fall 2026 as currently projected or later, cyclists and pedestrians crossing Wisconsin Avenue will very likely do it the same way the interim surface trail already does it now: at grade, waiting for the light, sharing the intersection with cars and eventually with the Purple Line itself. The tunnel that justified nine years of construction disruption at that specific crossing was never actually built. It was budgeted out before most of the construction most people associate with this project even started.

Getting across town right now

Until the trail reopens, the official workaround is the Georgetown Branch Trail Detour, which routes trail users onto Jones Bridge Road. It's a busy road without a shoulder or a marked bike lane, and the Washington Area Bicyclist Association has published lower stress alternatives for anyone who'd rather not share that stretch with commuter traffic. If you're looking for a recreational loop instead of a direct link, the open portion of the Capital Crescent Trail still connects to the C&O Canal Towpath and the Rock Creek Trail, which together allow for a roughly 22 mile circuit that never touches the closed section at all.

Worth knowing if you're navigating any of this right now: Metro has suspended Red Line service between North Bethesda and Friendship Heights from July 6 through September 6 to accommodate Purple Line construction work, with shuttle buses covering the gap. That closure is still in effect as of this writing, so if your usual backup for skipping the trail detour has been hopping on the Red Line, that option won't be back to normal for a few more weeks.

What actually happens after "reopening"

The trail's fate is tied to, but not identical to, the Purple Line's own timeline. As of a ceremonial final rail installation on May 8, 2026, attended by Governor Wes Moore, Lt. Governor Aruna Miller, and Senator Chris Van Hollen at the future 16th Street-Woodside Station in Silver Spring, the overall project was about 90 percent complete. Purple Line officials have said they're still targeting late 2027 for full passenger service, even after Van Hollen suggested he'd give the project some leeway into early 2028.

The reason the trail can plausibly open well before trains start running is that MCDOT takes ownership of the completed trail once construction on that piece wraps, independent of when passenger testing and service actually begin on the rail line itself. That's the same decoupling state officials pointed to back in 2024 when they first floated a spring 2026 trail date ahead of rail service. It's a real distinction, and it's the reason "the trail is basically done" and "the Purple Line is running" have never meant the same thing on this project.

If you want the broader context for why every date on this project has moved at least once, a 2025 review by the Maryland comptroller's office found that permitting and legal fees alone, originally budgeted at $6 million, had actually consumed roughly $800 million, driven by lawsuits and contract renegotiations. Total project cost has climbed to an estimated $9.53 billion, up from an original 2016 budget of $5.6 billion. None of that guarantees the fall 2026 estimate holds either. It does explain why the coalition that has tracked this trail since 1986 still hedges its own website with the word "tentatively."

If you've been in Bethesda long enough to remember what this trail looked like before 2017, you already understand something that doesn't show up in any press release: the neighborhood's daily rhythms adapted around this closure years ago, and whatever version finally reopens will be judged against nine years of workarounds, not against the original plan. That kind of granular, lived-in read on how a neighborhood actually functions, block by block and detour by detour, is the same lens worth applying before a home purchase or sale here.
