PEI's first freeway segment?

(1/8) > >>

At least, that's what I'm calling it.

The province is in the process of building a bypass around Cornwall, to be completed later next year.  The bypass will run to the north of Cronwall and tie into the recently completed roundabout at TCH-1/PEI 248 at North River.

I found the EIS for the bypass and it's....interesting.  The way they describe the bypass, it is effectively a freeway segment.  There will be two interchanges along the bypass, a diamond at Cronwall Rd and a trumpet where it ties back into existing TCH-1 near Clyde River.  The remaining cross roads (including PEI 247) will be bridged.  These will be only the 2nd and 3rd interchanges on the island...the trumpet at TCH-1/PEI 1A being the only existing interchange.

The EIS notes the bypass will be a mix of 2 and 4 lanes but there are no maps or description stating where the transition from 2 to 4 will occur.  So it's possible the bypass will be mostly a Super-2 instead of a full 4-lane freeway.  But it will be fully-controlled access nonetheless.

(H/T yakra for the find)

Alps:
There are a lot of recent bypasses west of there. Current Google satellite imagery shows the eastern stub of the new bypass and, past an image seam at New Haven, several alignments (with road layer on) that were not yet built at the time of the imagery.

Yes…..a 6km section of TCH 1 was realigned between New Haven and Bonshaw to straighten and lessen grades on the highest point on the TCH on PEI at Strathgartney:

PEI might have had a ‘Super 2 Freeway’ segment as far back as the late ’60s when a Causeway (not a bridge) was proposed between New Brunswick and PEI. The alignment was graded between Borden and the TCH-1/PEI-1A interchange at Albany Corner and can still be followed in this Google view:

An overpass was even constructed to carry PEI-10 over this alignment at Carlton Siding and it’s still there in the middle of a farmer’s field:






But when the Confederation Bridge was built in the ‘90s….the new TCH alignment was kept closer to town passing near the new Gateway Village and Welcome Centre. It was thought that keeping traffic close would give the town a bit of an economic boost after the loss of the many ferry service jobs.

How would a causeway (earthen fill embankment in water body) construction have worked?  Isn't the water over 70 feet deep in places?  What about tides which are large in Northumberland Strait?
