Concrete finally here as construction impacts grow

Nearly a month after sidewalk reconstruction began on Mass. Ave. in East Arlington, contractor J.H. Lynch laid down the first patches of new sidewalk last Friday.

Instead of completing a block a week, finishing completely before moving on to the next segment, Lynch and Mass Highway have elected a longer work cycle.

Sidewalk work began on September 24, meaning that in the west-most stretch of the project zone the sidewalks have been torn up for 4 weeks. By Friday construction had advanced as far east as Everett Street.

On Friday workers filled wooden forms with concrete, skipping every other form to allow access to the wet stuff. Presumably the skipped forms will be filled next week, when Friday’s pavement will be walkable.

Alternating segments of pavement makes work easier, but left the sidewalk by Dunkin Donuts in rough shape over the weekend.

Hopscotching like this leaves the sidewalk even less accessible, temporarily, than it was torn up.

That’s unavoidable, but because Lynch started this work on Friday the sidewalk has been left this way for the entire weekend. Or perhaps the sidewalk needs 72 hours to cure in any case.

A work crew started building the forms on October 14, the day after the Columbus Day holiday.

Other crews were busy last week removing sidewalk eastward and performing other work.

More sidewalk forms, getting ready for the pour, on October 13.

The segment inside each form is divided into 3 squares by control joints to prevent cracking.

The weather forecast for next week calls for cool temperatures, which will inhibit curing, followed by rain later in the week.

The sidewalks were filled and graded starting the week of October 6.
