Narrative:

Upon arrival we were vectored for a visual approach. When we put the gear down we got an EICAS message lg air/ground fail and the gear indicators went directly from 3 up to 3 down with no in transit indications. We were vectored off the approach and performed the applicable checklist. After the checklist was completed we declared an emergency and requested crash fire and rescue and to fly by the tower for visual confirmation of gear position. We then briefed the flight attendants and passengers and performed the fly by. Tower informed us that the gear appeared to be down and normal. We were then vectored back for an approach to. During the vectors we called ops to coordinate a maintenance inspection. We landed and stopped on the runway and; for safety; we had the gear inspected by maintenance before taxiing back to the gate. Upon gate arrival I made the appropriate logbook entries and contacted dispatch and maintenance.
