We present $u'g'R$ optical images taken with the MMT/Megacam and the Subaru/Suprime of the Extended Groth Strip survey. The total survey covers an area of about $\sim 1$ degree$^2$, including four sub-fields and is optimized for the study of galaxies at $z\sim3$. Our methods for photometric calibration in AB magnitudes, the limiting magnitude and the galaxy number count are described. A sample of 1642 photometrically selected candidate LBGs to an apparent $R_{AB}$ magnitude limit of 25.0 is present. The average sky surface density of our LBGs sample is $\sim$ 1.0 arcmin$^{-2}$, slightly higher than the previous finding.
