Montevideo Road is closed for construction between the intersection of Route 1 (Washington Blvd) to approx 3/4 west of the intersection of Montevideo Road and Dorsey Run Road. More information on timelines can be had by calling the Highways Dept in Howard County at 410-313-7450.
I see the closure, and i also see that you tried to edit the segment. Unfortunately adding an additional segment on top of the old one and changing the turn restrictions is not exactly the right way to add the closure.
I cleaned up the segment, but because it was recently touched (today) we will need to wait until the segment updates. Once it updates we can add a real time closure on the segment where it marks it closed.
I am also going to send you a private message here with some tips and guidance for editing, if you would like to get involved. We have a whole community that helps keep the map up and running.
