On the first street, 2/3 of the lights do not work. This means that 1 - 2/3 = 1/3 of the lights do work.
On the second street, 1/6 of the lights do not work. This means that 1 - 1/6 = 5/6 of the lights do work.
To find the total fractional portion of the nonworking lights on these two streets, we add the fractional portions that do not work on each street: 2/3 + 1/6 = 4/6 + 1/6 = 5/6
Thus, the total fractional portion of the nonworking lights on these two streets is 5/6. Answer: \boxed{\dfrac{5}{6}}
