Left: OK-51 westbound exit sign.
Although 51 is not an expressway in this area (just a 4-lane divided highway),
a trumpet interchange is used to keep the traffic flowing smoothly in all
three direction.
Right: the south end of 151. Mannford (51-east) is a regular diamond
exit, while Tulsa (51-west) is the trumpet interchange's sole cloverleafish
loop.
There is no "End" notification on either end of 151.

Above left: the Keystone Expressway's first BGS for the Keystone Dam
exit. Like the southern terminus, this is a trumpet interchange.
Above right: view down 151 at the point where the two exit ramps converge.
Lower left: a little further down the road, at the first assurance sign
after the convergance. In case you haven't realized it yet, those cars on
the road are traveling over the dam.
Lower right: northbound 151 at the point where you have to choose which
direction on the Keystone Expressway you want to go. As is the case along
much of this stretch of the expressway, junction signs for US-412 do not
show up, as 412 is a recent addition in this part of the state, and as signs
for US-64 already exist, putting up signs for 412 would probably also mean
changing the ones for 64, and that costs money the state doesn't have.
Just as I got back underway after taking the last picture, a couple
of deer darted across the road (I learned the next day that mating season
had just begun). The deer were moving, therefore so was the camera so excuse
the blurriness, but at left is a snap I got off of the second deer as it
was crossing the road (don't know how deer-chasing goes during mating season,
but if it's anything like the human variety I would assume this one's the
male). Click on the picture to see an expanded view, showing where the deer
was with relation to the road (at the time I was about even with the dual
US-64 signs in the lower-right picture above).
