Because of the imposing geography of nearby mountains, including Cadair Idris, and the Dyfi estuary, there is little space to practically put a road on, and consequently the road network today is more or less unchanged since classification.
The town is a significant bottleneck on the Welsh road network, as all traffic in the area has to pass over the Dyfi bridge. Because that is a Grade II listed structure, it cannot simply be widened and replaced, and requires regular repair due to HGVs striking the bridge. Strikes can result the bridge being closed, requiring all traffic to take a 20 mile detour, including one notorious incident in 2010 where it was closed for several weeks. A further problem is a bridge under the local railway next to the station, which regularly floods.
Transport Wales are currently investigating options to alleviate traffic. These include a new A487 bridge (either upstream or downstream of the existing one), widening and strengthening the existing bridge, and additional flood mitigation. Work is hoped to start in 2016.
