Abstract: The concentrations of some selected heavy metals in roadside soil samples collected from the major road networks of Dass, Bauchi State, Nigeria were determined using Atomic Absorption Spectrophotometry. The levels of chromium, cadmium, nickel, lead, copper, manganese, iron and zinc investigated ranged from 0.00 – 0.50, 0.33 – 0.67, 2.50 – 11.67, 0.33 – 3.67, 14.83 – 38.17, 5.00 – 53.33, 108.33 – 531.67 and 57.83 – 79.83 mg/kg respectively. Soil samples from Dass – Zwal road network contain the highest concentrations of chromium (0.50 mg/kg), nickel (11.67 mg/kg), copper (38.17 mg/kg) and iron (531.67 mg/kg) respectively. Soil samples from Dass – Bauchi road contain the highest levels of cadmium (0.67 mg/kg) and zinc (79.83 mg/kg) respectively. Soil samples from Dass – Mbak road network contain the highest concentration of lead (3.67 mg/kg), while samples from Dass – Bununu road network contain the highest concentration of manganese (53.33 mg/kg). The variations in the concentrations of nickel, copper, manganese and iron in all the road networks were found to be statistically different as revealed by Least Significant Difference test (p
