Reader board taken down on Bogus Basin Road; left-out turn on Americana Boulevard at Shoreline Drive will not get a flashing yellow arrow signal; origin of Black Cat Road name may be lost to history but Ten Mile and Five Mile roads likely named for creeks.

The Road Wizard Replies

Dear Road Wizard: Why has the reader board on Bogus Basin Road been out this winter and is it coming back? It was always helpful for current info. Miss it.


Road Wizard:

The "snow" board was originally installed by ACHD on Bogus Basin Road north of Curling Drive as a way for ski resort staff to display real-time weather conditions, crash alerts and parking information.

But it became more of a tube hill status report during the last few years of operation. Eventually the aging sign was taken down by ACHD because parts were becoming hard to come by, and repairs were more time consuming. Nearly all ski operations-related information can be found through multiple types of electronic devices anyway.

The sign remnants will be removed in the future because some of the infrastructure will be in the way of an upcoming sidewalk project scheduled in a couple of years. The plan is to connect existing sidewalk further up Bogus Basin Road with Curling to provide a walk route to Highlands Elementary School.

Dear Road Wizard: Could you please implement the flashing yellow left-turn arrow in the northbound direction of Americana Boulevard at the intersection of Americana and Shoreline Drive? It is implemented in all three other directions but not that one.


Road Wizard:

You have already waited a while for an answer to this question but you will also still have to wait at that signal without a flashing yellow arrow.

ACHD carefully considered installing the signal at this "left" out turn. In fact the agency has evaluated nearly all of the 430-plus signalized intersections in Ada County for the use of flashing yellow arrow signals.

At Americana and Shoreline, sight distance for northbound left-turning vehicles is compromised because the oncoming traffic approaches at a curve. This can cause tall vehicles in an oncoming lane to block the view of vehicles in the other through lane. There is a lot of big-sized vehicle traffic at this intersection due to the nearby post office, so a yellow arrow signal is not planned.

 Dear Road Wizard: I have lived in this area for a little over two years. I am interested in how some roads got their names but three in particular. One is Black Cat Road. We spoke with a historian and they could not fully explain the origins of the name except to guess. The other two have to do with Ten Mile and Five Mile roads. They are probably 10 miles and five miles from something but I don't think they are tied together because they are six miles apart. Is it possible to find out how the names came about?


Road Wizard:

A common explanation for Five Mile and Ten Mile is that they were named after creeks by those names. And those creeks were those distances from the Boise River, or perhaps Boise itself.

The origin of the name Black Cat Road may be lost to history. The daughter of the original owners of the Kit Kat Klub building at Black Cat and Franklin Road lived on Black Cat in the 1940s. Her family even named their club "Black Cat." There was also a Black Cat farm at the time. But the road was called Black Cat before all of that and apparently the explanation for the name wasn't clear even back then.
