Mallam junction road to be closed for reconstruction Portions of the Mallam junction road are to be closed for major drainage works to reduce the perennial flooding on the stretch. Every year the Mallam Junction section of the N1 highway is rendered completely impassable when it rains with residents blaming it on a total filling station which they say had blocked the water way. The project under the GAMA project will include the cutting through the road. GBCONLINE ---DECRYPTED---
