There is indeed enough space on both sides, except for the auto repair shop--an small, cheap and expendable building. It's a little tricky at Old Weston Road with the historic Heydon House on the northwest corner, but the roadway could shift slightly to the south. Alternately, an additional lane could be built where the existing sidewalk is (up to almost the facade of the building), with an arcade built through the Heydon House for pedestrians. The arcade would open up onto the sidewalk continuing west of the building.
Something like this:
Could work, as a plan B. Though sifting the roadway south should be part of plan A.
