The road construction on 4 heading to calvert, right at oak drive and further down. Why are they driving in pretty stout re-bar into the hills? The slope doesn't so bad that grass wouldn't hold the hill. Wouldn't think slope would require a concrete base?

Traffic flow increase might drive the requirement for a noise reduction wall.
Well, if you live 100 feet away, that's better than the noise
Don't know the job but do similar for a living. What are they building? Give me details and I can likely give some reasons.
Either more details or I'd have to see it myself (or a pic). If they're widening the road into a hill, it could be several things.
The comment above about "prior to the rebar going in and filling with concrete" seems backwards, but if they earth under the proposed road is in poor shape, it could be reinforned and supported by caissons. Now, you'd typically auger our or drill a void - place reinforcement and THEN pour concrete. This creates, in sense, a pier piling to which the roadway structure could be placed upon. Seems like a lot of work for a widening and there also seems to be other options available. Unless of course the area is general bad (very wet, marshy, etc.).
Another thought was that if the rebar was being "driven" - could it be they are tiebacks for a retaining wall intended to hold back the slope. If the widening would cut into the hillside, they would have to hold back the earth in some manner. Seems excessive (in terms of rebar amount) if they hill is a gentle slope.
Only get glimpses of the operation when driving by. They had a machine with a hose attached with a long nozzle filling the re-bar holes. All of the re-bar rods are implanted on the slope(s) that lead down to what I assume is a road bed.
Clear as mud huh? Got the picture in my head, sorry I couldn't convey it better with this post...
I think it's just forking genius of them to widen the road without widening the bridge.
The idea is to move the traffic backup off of 235 and onto rt4..
