We present u',g' R optical images taken with the MMT/Megacam and the Subaru/Suprime telescopes of the Extended Groth Strip survey. The total survey covers an area of about similar to 1 degree(2), including four sub-fields and is optimized for the study of galaxies at z similar to 3. 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 Lyman-Break Galaxies (LBGs) to an apparent R(AB) magnitude limit of 25.0 is presented. The average sky surface density of our LBG sample is similar to 1.0 arcmin(-2), slightly higher than the previous finding.
