Bids for the first design contracts on the Trump Administration’s plans for a U.S., Mexico border wall are due Tuesday.

And while it’s unclear how many contractors will apply, the Associated Press reports more than 200 companies signed up for email notifications on the project’s website for contractors lists. Chosen prototypes will be built on an approximately quarter mile strip of land in San Diego. Costs are estimated to reach $200,000 to $500,000 for each model.

But how effective will a wall really be? And what evidence can we draw on from past attempts at curbing illegal immigration?
