From DDOT:
"The District Department of Transportation (DDOT) is scheduled to temporarily close lanes on the eastbound side of the Southeast Freeway this weekend to complete the demolition of two RFK access ramps. The ramps cross over the freeway.
"Last Saturday, crews demolished the concrete on the ramps; this weekend they will remove the steel structure. The work is scheduled to take place from 5 am to 10 pm on Saturday, January 16. There could be additional closures on Sunday, January 17, but only if the work is not completed on Saturday.
"The left lane and shoulder will be closed just prior to the I-295 South and Pennsylvania Avenue split. That means all traffic approaching the split will have to take the I-295 exit. There will be no access to RFK Stadium or Pennsylvania Avenue from the SE Freeway."
They haven't posted the new advisory yet, but here's the
link to last weekend's, with the graphics for detours and whatnot. Expect delays on the freeway.
