The eastbound U.S. 36 off-ramp to Sheridan Boulevard will be closed nightly today through Saturday, and the off-ramp to Federal Boulevard will be closed today through Wednesday in connection with work on the U.S. 36 Express Lanes project.

The Sheridan off-ramps will close nightly at 10 p.m. today through Thursday, reopening at 5:30 a.m. the following day. Friday and Saturday, the closures will start at 11 p.m. and run through 8 a.m. the following day, according to an email update about the project sent by the Colorado Department of Transportation. The closures are needed for drainage and wall installation.

There also will be single lane restrictions on the Sheridan off-ramps from 9 a.m. to 3 p.m. today through Saturday for bridge excavation work. One lane will remain open on each ramp, according to CDOT.

The closures of the off-ramp to Federal will start nightly at 6 p.m. today through Wednesday, reopening at 5:30 a.m. the following day. The closures are needed for barrier construction, according to CDOT.

In addition, there will be closures of various off-ramps from 9 p.m. to 5:30 a.m. through Saturday as eastbound traffic is routed on to new concrete pavement. The closures, which CDOT said will occur at various times, are: the eastbound U.S. 36 off-ramp to West Flatiron Crossing Drive, the eastbound U.S. 36 off-ramp to Interlocken Loop, the Interlocken Loop on-ramp to eastbound U.S. 36 and the East Flatiron Crossing Drive on-ramp to eastbound U.S. 36.

CDOT said no two consecutive ramps will be closed at the same time and encouraged drivers to use alternate routes as much as possible to avoid the area.

Other closures to expect this week in connection with the project include:

Today through Saturday:

• Single lane restrictions on eastbound U.S. 36 from east of Church Ranch Boulevard to Federal Boulevard from 10 p.m. to 5:30 a.m. for wall and barrier construction, grading and paving.

• Single lane restrictions on westbound U.S. 36 between Federal and Sheridan boulevards from 10 a.m. to 3 p.m. and 8 p.m. to 5:30 a.m. The restrictions are needed for median barrier demolition, wall installation, grading, paving and concrete hauling, according to CDOT.

• Single lane restrictions on eastbound and westbound U.S. 36 from 88th Street to Wadsworth Parkway from 9 p.m. to 5:30 a.m. for dirt and concrete hauling, paving, striping, temporary barrier placement, surveying and repairing potholes.
