Dubuque-Wisconsin Bridge


US 151 is a US Highway in the US state of Iowa. The road forms a north-south route in a northeasterly direction in the east of the state. The road begins at a junction with Interstate 80 and continues through Cedar Rapids to the Wisconsin border in Dubuque. The road is 170 kilometers long.

Travel directions

US 151 at Dubuque.

US 151 begins 140 miles east of Des Moines at a junction with Interstate 80. The road heads north through the Iowa River valley. This is a single carriageway up to the Cedar Rapids conurbation. US 151 does not pass through downtown Cedar Rapids, but follows the south and east bypass. The southern bypass coincides with US 30 and is part freeway, including interchange with Interstate 380. Southeast of the city, one crosses the Cedar River, after which US 151 turns north and follows the eastern bypass, a 2×2 divided highway with at-grade intersections to the suburb of Marion.

From Marion, US 151 heads northeast as a 2×2 divided highway to Dubuque, with bypasses at Anamosa, Monticello, and Cascade. On this route, US 151 crosses some wooded river valleys, with flatter agricultural land in between. On the nearly 100 kilometers between Cedar Rapids and Dubuque, there are no other major roads to cross. Just before Dubuque, the double numbering begins with US 61, which continues into Wisconsin. The road runs as a semi-highway through Dubuque and crosses the Mississippi River via the Dubuque–Wisconsin Bridge, before continuing on US 151 in Wisconsin towards Madison.


US 151 was created in 1926, but then ran exclusively in Wisconsin. In 1938, the southern terminus was changed from Madison to Cedar Rapids. In 1985, the route was extended even further south to I-80 in Iowa County.

In 1902 the Eagle Point Bridge opened at Dubuque over the Mississippi River. It was replaced on August 21, 1982 by the wider Dubuque–Wisconsin Bridge. US 151 is of particular interest between Cedar Rapids and Dubuque, and is also a continuous 2×2 lane road here, although there are only a few grade separated intersections. The doubling to 2×2 lanes started in the second half of the 1990s, initially between Cedar Rapids and Anamosa, and in the first half of the 2000s between Anamosa and Dubuque.

Traffic intensities

The road counts from 1,800 to 6,800 vehicles for Cedar Rapids and 19,200 on the southern ring road. The eastern ring counts 12,200 vehicles and descending from 11,100 to 5,300 vehicles drive to Dubuque. 18,400 vehicles cross the Wisconsin border.

US 169 is a US Highway in the US state of Iowa. The road forms a north-south route through the center of the state, remotely parallel to US 69 and Interstate 35. The road doesn’t connect any major towns, but it does pass just west of Des Moines. The route is 385 kilometers long.

Travel directions

US 169 in Missouri comes from St. Joseph and continues its route in Iowa through a fairly monotonous countryside, with rolling meadows. US 169 is almost entirely a single-lane road that passes through a number of smaller towns. US 169 runs parallel to Interstate 35 for 25 to 70 kilometers and therefore bypasses most of the larger towns in central Iowa. US 169 passes just west of the Des Moines metropolitan area . Also, US 169 forms Fort Dodge’s western bypass, which is partially 2×2 lanes. North of Lakota it follows the border with Minnesota, then US 169 in Minnesota continues to Mankato.


US 169 was created in 1930. The route hasn’t changed significantly in Iowa since then. It is not a very important route due to alternate north-south routes in the region such as I-35 and the lack of major towns in the region. The most important place is the town of Fort Dodge, where US 169 was widened slightly to 2×2 lanes around 1990.

Traffic intensities

The road is often quiet, with between 500 and 1,500 vehicles per day, only at Adel and Fort Dodge the road is a bit busier with 5,000 and 8,700 vehicles respectively. About 900 vehicles cross the Minnesota border every day.
