Highway Map (click to enlarge) Names Start Terminus Length (km)
RR 305
RR 305 RR 305 Sydenham Rd. Dundas west town limits, along railway tracks (continues from RR 505) King St. (ON 8), Dundas 2

Although CR 5 existed by 1960, the road originally ended at the town limits, leaving the segment within Dundas unnumbered.
RR 308
RR 308 RR 308 King St.
Main St.
Osler Dr. 		Bond St., Dundas Dundas east town limits (continues as RR 108) 4

Concurrent with: ON 8. "308" was an internal designation used to refer to the portion of the highway in Dundas covered by municipal maintenance. It was never signed this way in the field.

Succeeded by: RR 8 (King Street portion).
RR 330
RR 330 RR 330 Ogilvie St. (1979) Governors Rd., Dundas Old Ancaster Rd., Dundas insignificant
(1984) King St. W., Dundas Governors Rd., Dundas insignificant

Previously: ON 5B, ON 99, RR 46; 1984 segment only.

Adjustments: Strangely, RR 330 seems to have completely shifted during its brief existence. Hamilton-Wentworth's 1979 regional road plan defines it as the south half of Ogilvie Street, with the north half left undesignated. 1984 maps depict it as the north half of Ogilvie, with the south half unnumbered! Governors Road serves as the dividing line between both incarnations.
RR 331
RR 331 RR 331 South St. Old Ancaster Rd., Dundas Osler Dr. (ON 8), Dundas insignificant

Added in 1979; probably unnumbered before.
RR 332
RR 332 RR 332 Old Ancaster Rd. South St., Dundas Dundas south town limits (continues as RR 232) insignificant

Despite the age and gravity of Old Ancaster Road as one of Dundas' oldest roads, it was numbered as a Regional Road for only a very brief time. RR 332 was added to the system in 1979, and had vanished from maps by 1984!
RR 341
RR 341 RR 341 King St.
Cootes Dr. 		Main St. (ON 8), Dundas Dundas east town limits (continues as RR 141) 2

Previously: ON 102 (1947-1964).

Succeeded by: RR 8, which is still in commission today.
RR 344
RR 344 RR 344 York Rd.
Olympic Dr. 		ON 6, north edge of Dundas Cootes Dr., Dundas 5

Previously: RR 44 (York Road portion). Partially realigned from that road's original incarnation.
RR 354
RR 354 RR 354 York St. Main St., Dundas King St. (ON 8), Dundas insignificant

Previously: RR 44.
RR 364
RR 364 RR 364 York Rd. Olympic Dr., Dundas King St., Dundas 2

Previously: RR 44.
RR 399
RR 399 RR 399 Governors Rd. (1979:) West of Bridlewood Dr., Dundas Main St. (ON 8), Dundas 2
(1982:) Binkley Rd. west of Dundas (continues from RR 299) Main St. (ON 8), Dundas 6

Previously: ON 5B (1938-40), ON 99.

RR 399 was originally an internal designation used to refer to the portion of ON 99 under municipal maintenance. After ON 99 was decommissioned in 1982, the "399" designation was expanded to encompass the entire highway in Dundas. It also began to be publicized on maps, and (probably!) signed in the field.

Succeeded by: RR 99, which is still in commission today.
