We warned you that the 'Octojam'/Rampture at the 405 and Wilshire Boulevard would be starting up this weekend. But if you actually live or work in the area, you might have found it hard to wrap your head around just how badly the reconstruction of the eight on and off-ramps will affect your commute.

A web programmer at UCLA Joe Maddela with this exact problem came up with a simple programming tool called the Rampture Calculator. It's pretty easy: you plug in the ramp that you're using and the calculator spits out how just many days (at most) your commute will be affected, according to Metro estimates.

L.A. Streetsblog did a Q&A with Maddela about why he created the simple tool:

I commute daily to UCLA on the 405 freeway and my main exit is Wilshire. I was trying to calculate how long I’ll be impacted by the closures which can last up to 90 days for some of the ramps. I quickly got frustrated having to search for the info, downloading a PDF, and then figuring out my on ramp/off ramp combination.

The program is simple but it does help to take a lot of hard-to-navigate information from the Metro site and boil it down to the one question everyone wants to know about the project: just how badly are the closures going to affect me? Just how badly the closures will end up affecting surface streets used for the detour is a whole other question entirely. We hope it works out since there's not much of a Plan B. We'll keep our eye on Google Maps' traffic function in the meantime.

Here's a run-down of the project from Metro:
