(Updated at 4:40 p.m.) A dump truck overturned on N. Glebe Road, right before Chain Bridge, completely blocking the road to and from the bridge.

The driver was reported to be “severely trapped” in the truck’s cab, prompting a large fire department rescue response, according to scanner traffic. Multiple ambulances were dispatched to the scene, though it’s unclear if anyone else was injured.

The crash also spilled the truck’s load of cinder blocks and construction debris over the roadway. A heavy wrecker was requested to respond to the scene to assist with the cleanup.

The truck crashed after a steep and winding section of Glebe Road, which leads to a traffic signal at the intersection with Chain Bridge Road, just prior to the bridge.

Chain Bridge was expected to remain closed between D.C. and Virginia, and northbound Glebe Road is expected to remain blocked at N. Military Road, for an extended period of time — likely for “several hours.” Heavy traffic was reported on Chain Bridge Road approaching the crash scene this afternoon, with backups starting to extend into Fairfax County.

“Expect major delays as rescue work continues,” advised the Arlington County Fire Department. “Seek an alternate route.”

“Disruptions are anticipated into the evening commute,” Arlington County said via Twitter.

After an extended rescue operation, the trapped driver was removed from the truck just prior to 1 p.m. Glebe reopened to traffic between Chain Bridge Road and Military Road around 2 p.m. Chain Bridge reopened around 4:30 p.m., according to scanner traffic, though for now traffic heading from D.C. must turn on to Chain Bridge Road.

UPDATE – Chain Bridge itself remains closed for clean-up. Glebe Road and VA side of Chain Bridge Road are open to traffic. Vehicles still can not cross bridge in either direction. Follow @arlingtonalert for road information — Arlington Fire (@ArlingtonVaFD) October 7, 2019
