Sharjah to Lamcy plaza (Bus or Metro) ?

for the metro you have to wait until green line opens in August this year. But it will be within Dubai because no metro train in Sharjah. You will ride from Dubai police HQ station or the one next to Lulu on the green line , and you will get off at Oud Metha station (next to Rashid hospital), then 10 minutes walk to Lamcy or take one of the feeder buses there stopping at Lamcy center.
