^ That is true, I underestimated that distance in my head.

Both the left and right shoulder on the approach would need to taper down around 400-500 ft Iím roughly guessing, and assuming a 70 mph design speed.

However, immediately on the other side of the bridge, the shoulder can just appear again fully, it doesn't need to taper back.

The outside shoulders can appear fully once the roadway clears the bridge on the departure end. However, the inside (median) shoulders, if they were tapered in, would also need to be tapered back out if there was an associated travel lane shift to shoehorn 4 lanes into the space.

Moose:
That railroad bridge dates from the initial construction of 465.

Look at the 6th flat area from the right of the bridge. You can still faintly see the mounting plate for a Pennsylvania Railroad Keystone sign.

This bridge once had a twin (built about the same time).. it spanned I-65 in Jeffersonville.



The railroad at this point, belongs to the short line Louisville and Indiana. However CSX has an easement agreement over the line.

The L&I still incorporates the PRR "keystone" in its logo. Maybe the new bridge gets a similar logo sign?

I-69/I-465 system interchange work zone; looking northwest from the under construction Epler Avenue bridge that will go over I-69 in southern Marion County. Eight lanes of I-69 will be placed on the raised earthwork berm. The natural gas-fired Harding Street Generating Station is in background right.


Slightly closer look. While a good amount of pile driving has been completed for the interchange's bridges, work continues to finish up.


Closer look using the long range lens. Note the pile driving rig on the right.


Turning around, the view looking southeast from the Epler Avenue bridge. I-69 will be coming right through here.


Different perspective showing what seems to be the on-ramp (on the right) from Epler Avenue to southbound I-69. Only a partial interchange will be built at Epler ó a northbound off-ramp and a southbound on-ramp.


Epler Avenue; looking west from the bridge that will take Epler over I-69. The coated rebar will support the raised concrete median. Hard to believe this is in Marion County. There's a old neighborhood down that way called Sunshine Gardens, which features houses on large lots. This was discussed a few pages back. In the opposite direction, the area is light industrial.


Another view of the I-69/I-465 system interchange work zone; looking northwest.


Bundles of rebar on the Epler Avenue bridge; looking west.


Another of the system interchange work zone; looking northwest. I-465 is located in the background.


View using the long range lens looking southeast from the Epler Avenue bridge; State Road 37 in the background.


And another looking southeast from Epler.


One more of the system interchange work zone.

More pics to follow.
