E Grand Avenue Complete Streets Conversion

Grand Avenue from 2nd Avenue to E Pennsylvania Avenue


The E Grand Avenue Complete Streets Conversion Project is a Connect Downtown pilot project. The goal of the project is to provide better access for all users (pedestrians, transit uses, bicyclists, and vehicles) while also increasing safety for everyone. Safety is improved by reducing vehicle travel lanes, enhancing pavement markings with colored and more visible markings, and improving pedestrian crossings at intersections. These changes are expected to lower vehicle speeds and make the corridor more desirable for all users.

Protected bike lanes are different from conventional bike lanes where the bike lanes are placed along the curb and protected from vehicle traffic. It is the first of its kind in the City of Des Moines. This project is meant to be constructed with low-cost, temporary improvements to give the City time to see how the concept functions. This trial period also allows the public to get used to new configuration and provide valuable feedback to the City on what works and what doesn’t. The hope is after the pilot program (approximately 2 years), a more permanent solution with raised median, landscaping, and more durable pavement markings can be completed. 

The E Grand Avenue Complete Streets Conversion Project will reconfigure the existing lane layout of three traffic lanes (2-WB, 1 EB), a westbound bike lane, and curb parking on both sides. The new configuration will include 1 traffic lane in each direction, parallel parking on both sides, a 3’ painted buffer lane, and protected bicycle lanes in either direction. The bike lanes will be along the curbs to completely separate the bike lane from the vehicle traffic. The intersections will include painted medians with vertical delineator poles to provide a better protected crossing for bicyclists and pedestrians. The corridor will also include green conflict zone markings to notify drivers of the presence of bicyclists. Bus stops will include raised islands for increased visibility.

The project will be constructed in 2 phases. The first phase will be from Robert D. Ray Drive to E Pennsylvania Avenue. This project will include a full day closure(6:00am-6:00pm for contractors to apply a thin pavement overlay (fog seal) to provide a uniform base and make the new pavement markings more visible. After the full closure the remaining pavement markings, vertical delineators, and bus stop improvements will be completed. The pavement markings will be completed over night over the course of approximately 3 nights. Based on the signed contract, the Contractor will have 2 weeks to complete this work. Parking along Grand Avenue will be restricted on certain blocks depending on what work is happening.

The remaining work from Robert D. Ray Drive across the Grand Avenue Bridge to 2nd Avenue will be completed with the Bridge Project. This portion of the project will connect to the existing bike lanes along Grand Avenue and provide a continuous westbound bike lane from the Pappajohn Sculpture Park to the State Capitol.

Project Updates (6)

Delineator Post Changes
by C. Bogenreif on October 16, 2017

Starting today, construction crews will be out on E Grand to relocate the vertical delineator posts between the parking and bike lanes. The posts are being moved to allow for more space for vehicles to park and move the parked vehicles away from the travel lanes. One of the top concerns from the public with this pilot project is that the lanes are too narrow and parking is too close to the travel lanes. Moving these posts should help address those concerns. 

If you have any comments or questions we could love to hear from you. Please follow the link on the project page to the Wikimap where you can add comments and see what other comments have been submitted.

E Grand Pilot Update from City

Bus Stop Enhancements
by C. Bogenreif on September 22, 2017

Starting the week of September 25th new raised bus stops will be installed along E Grand. The bus stops will be located westbound at E 6th Street, E 4th Street, and Robert D Ray Drive as well as at E 6th Street for eastbound buses. The raised bus stops will provide a waiting area for transit users between the protected bike lanes and vehicle travel lanes. The construction of these bus stops will last through the week of October 6th, weather depending. 

Project Feedback and How-To Graphics
by C. Bogenreif on September 05, 2017

As people get used to the new configuration of the E Grand Complete Streets Pilot Project we want to hear from you! Please check out the updated resources panel on the Project Page that includes a link to an interactive Wikimap that allows you to provide vital feedback on what works, what doesn't, and how we can improve the E Grand corridor.

Also new to the resources panel are How-To graphics that explain different aspects of navigating the new configuration. Please take a look to get a better understanding of the ins and outs of the project.

 Quick Project Update - Most of the major work has been completed. Some upcoming work may require some minor traffic impacts but no fill road closures are expected. The final green intersection pavement markings will be completed by the end of the week. These markings include the two stage left turn bike boxes at the intersections of E 4th, E 5th, and E 6th. The raised bus stops will be constructed before the end of September with minor traffic signal improvements and improved signage to follow.

Pavement Marking Schedule
by C. Bogenreif on August 24, 2017

Due to weather delays earlier this week the pavement marking schedule has been pushed back. The pavement markings will be completed overnight with the street closed in sections to allow most side streets to remain open. Below is the updated schedule, weather depending:

Thursday, 8/24 at 6pm to Friday, 8/25 at 6am Robert D Ray to E 4th Street
Monday, 8/28 at 6pm to Tuesday, 8/29 at 6am E 4th Street to E 6th Street
Tuesday, 8/29 at 6pm to Wednesday, 8/30 at 6am E 6th Street to E Penn Ave
