Here is a novel suggestion regarding the Capital Street crossing safety issue: Many European communities have barriers that rise from beneath the pavement.
They secure pedestrian paths, especially near government buildings and city centers. These posts redirect traffic flow during certain hours of the day, but are otherwise retracted for the convenience of the neighborhood.
The pylons could be up during school hours and down for evenings, weekends and summers. The school district’s installation costs could be justified as being in the best interest of the students, and a permanent closure of the street would be averted.
This might be an acceptable compromise for both sides in the coming discussion of the Capital Street closure.
